The Bill Phillips Body For Life Inspired 10 Minute Warmup

A bit over 20 years ago, I bought the famous Bill Phillips book Body For Life. I won’t go too much into the premise of the book, its historical context at the time or its many flaws (including in-book product promotion). At the time, I found the template for fitness and diet interesting, so I bought it and followed the plan.

The book’s training method had you aggressively strength-train several days a week and follow some simple diet principles. For “cardio”, it had you do 20 minutes of effort-based high intensity intervals, which you can do in any aerobic-based way you desired, three days per week. I always used the treadmill. Back then I wasn’t the focused runner I am now, nor was I active beyond walking or cycling to commute, but I had enough fitness to run hard for some distance.

In short, the Cardio:

  • You start at a 5 out of 10 effort, whatever you feel that means
  • After two minutes you increase to 6 out of 10.
  • Each minute thereafter you again increase effort by 1, until you do a minute at 9 out of 10.
  • Then you scale back to 6 out of 10 for a minute, once again ramping each minute until at 9 out of 10, then falling back to 6 and repeating the process.
  • Once you get to 9 out of 10 for the 4th time, instead of dropping back to 6 you increase to 10 out of 10 and hold that for a full minute.
  • Then drop back to 5 and cool off for the final couple of minutes at 5 out of 10 to end the workout.

This workout always kicked me around, but I was always able to get it done. It was the only running I did, and you did it every 2-3 days so I had plenty of time to recover before the next one. I followed the Body For Life plan for a little while and then left it behind, probably in part because I lost gym access around that time.

In any case, this interval sequence resided in the back of my mind pretty much all this time. I still have the book but haven’t cracked it in a long while. The strength workouts I’ve forgotten as they’ve long since been replaced by far superior approaches.

But during recovery from my injury problems, as I started using the treadmill again, this approach came to mind as a warmup. It’s very similar to the 10 minute progressive treadmill warmup Lifetime Fitness taught me during my VO2max testing a while back. In that warmup, you jog for 2 minutes, and speed up by 0.4mph each 2 minutes before ending at a speed that is somewhat fast for you.

I realized that’s quite similar to how I did the Body For Life intervals. For 5/10 I would start at a 3.0mph walk. Then my 6 would be a fast 4.0mph walk. My 7 would be a 5.0mph slow jog. My 8 would be a 6.0mph steady run. My 9 would be a 7.0mph hard run. And the 10 out of 10 would be a nearly all-out (… well, at the time) 8.0mph run.

While the top intervals were harder than anything in the Lifetime warmup, the bottom intervals were of course much easier on me and allowed me to recover. The Lifetime warmup was harder to do because it required 10 straight minutes of progressively harder running (though, at least it was done after the fastest interval).

I realized doing an adjusted 10 minute version of the old Phillips workout as a warmup would be an easier and possibly more effective warmup, since I’d hit a faster top speed with a shorter duration, then have a walking period to cool off before re-trying.

I tried it recently and it not only felt better as expected, but I found it did a much better job getting my body ready to run at a higher intensity. So now that’s what I do as a warmup before any key indoor workouts (and you’ll notice I adjusted from the above paces a bit).

  1. I start at a 3.0mph walk for 1 minute.
  2. Increase to a 4.0mph power walk for 1 minute.
  3. Increase to a 5.0mph very easy jog for 1 minute. If too easy (e.g. I’m running into the front of the treadmill), I increase to 5.3mph, a more typical jog/recovery pace for me.
  4. Increase to 6.0mph steady run for 1 minute. If feeling comfortable after a few seconds I’ll often increase to 6.2mph.
  5. Increase to a brisk, somewhat demanding 7.0mph for 1 minute. If feeling comfortable after a few seconds I’ll often increase to 7.3mph.
  6. Drop back down to 3.0mph for 1 minute, and repeat the sequence.
  7. After the 10th minute, shut it down and go dynamic-stretch before the workout.

Since many of my treadmill sessions cruised around 5.5-6.5 mph, this whole sequence made that range feel very sustainable over a long period of time, suitably warming me up for a workout like that.

I not only do this warmup before treadmill runs but also do it before other cross training sessions, to ensure I’m at and can reach a suitable heart rate training range for a maximum training stimulus and benefit.

If I run near my gym, I could also do this warmup in the gym, then go outside and run. Sure, it can be awkward walking out of the gym 15 minutes after arriving, then back in the gym 45-75 minutes later.

I could also, with some discipline and adjustment, do the warmup outdoors by feel. That makes some sense after all, since the workout was originally intended to be done by effort rather than set parameters. I had an outdoor run yesterday that didn’t go great and had to be cut short. While not certain, perhaps it could have gone better had I thought to do an outdoor warmup like this.

You could follow the above sequence, with your own pace and parameters. Whatever a 5 out of 10 feels like or a 9 out of 10 feels like is up to you to determine (notice I don’t ever go to 10 out of 10, by the way; I stop at 9).

You could walk for 4 minutes and run just for 1. You could start at an easy run and just have it be all running. You could do it all on a spin bike or a rowing machine or elliptical. It’s up to you.

But I found this to be a great 10 minute aerobic warmup sequence, and it might work for you as well.

Building A Better Self: July 2021 Edition

I not only finished Friday with 34 miles this week, with this weekend and a long run workout still to come (after 36 miles last week), but I did so despite insomnia on Thursday night and my air conditioner problem messing with my sleep earlier this week.

While obviously tired, I didn’t feel burned out, and I had the energy in me to pump out 30-45 minute training workouts on the treadmill after work, AND run 1K-2K on all my work breaks (except only for Thursday afternoon, which I walked). I played everything by ear and was willing to bail on any of the above if I simply didn’t feel well enough to do it.

But I did all of the above. No stimulants (outside of the same 12 oz of coffee I have had every morning for years and years), no crutches, no supplements I hadn’t already been taking for a while. Even now, other than understandable general fatigue (and yes I got decent sleep last night), I feel okay.

How am I doing this? I haven’t taken a complete day off from training since June 23 (10 days ago)

There’s a few new things I’m consistently doing. Some regular readers already know about, but some things not as much:

The Idea of a Bad Workout

I don’t have bad workouts.

That’s definitely not because I’m perfect, or because I don’t challenge myself. And it’s not like I don’t have good workouts.

I’ve had plenty of workouts that didn’t go the way I wanted. I fail over and over again. I’ve had to cut workouts short, re-configure workouts, turn quality workouts into simple easy runs, stop the workout early and go home, etc.

But none of these workouts were bad. I didn’t screw them up… even if maybe I screwed something up (e.g. ran repeats too fast, went out too hard, didn’t bring hydration, ate or hydrated too much, etc).

I could give you a treatise on the perils of results based analysis, e.g. you ran a race and won, so you think therefore the way you ran the race was good… or you didn’t hit your goal time or finish despite following your race plan, and you decided therefore you screwed it up.

On a similar note, we as human beings often attach emotional judgment to our workouts and races. And so many have a workout not go the way they want and decide the workout was therefore bad. I see and hear this far too often.

To me, workouts are truly bad only if they set back your growth, fitness, or life… for avoidable reasons that were totally within your control.

  • Going out for a run if you’re injured and know you should rest, and aggravating the injury
  • You’re burned out and exhausted and know a run isn’t going to help you in any way, but you go and run anyway.
  • Running in a severe thunderstorm or tornado.
  • Chasing after someone while holding a knife, to try and end them.

As you can see, my threshold for labeling a bad run is somewhat higher than most people.

If I go out for a run, feel crappy the whole way, and don’t feel great when it’s done, I don’t consider that a bad run. I consider that a learning experience. Maybe I could have skipped that run. And now I know, thanks to that run, that maybe running in those circumstances isn’t the best idea or use of my energy.

Today I went out for speed intervals after yet another consecutive night of poor sleep (been having an unusual stretch of these nights recently). I was up for the run but my energy wasn’t high, and though I gave a solid 10K effort I couldn’t go as hard in the repeats as I would have liked.

I did knock out four solid repeats out of the five needed, but I knew while finishing the 4th that I was tapped and at the point where the 5th might push me too far for my good. So I stopped after that 4th and headed home.

Was it a bad workout because I never felt quite right, or because I couldn’t get myself to eke out one last repeat, or because I did them closer to threshold/10K effort than the desired 5K/mile effort?

Or was it a good workout because I made progress in my training plan, finished the needed workout minus just one repeat, didn’t lose any ground with training since I’m still in the base/foundational phase, and moderated my effort to where I felt more rewarded than worn out by a key workout in tired circumstances?

Recall I mentioned the value in giving every workout a purpose. On a similar note, if a run doesn’t go the way you want or doesn’t feel at all good, you can still take away some positive value from your workout. It’s rarely a total waste as long as you apply yourself.

Why Does Pachev’s Always on The Run Routine work?

I’ve talked before about Sasha Pachev, the prolific patriarch of the prolific Pachev running family in Utah. To this day, I still consider his simple advice among the most effective for marathon training. Much like Hal Higdon, Pachev preaches volume first through a consistent diet of easy running, before progressing to a simple but consistent variety of speed and tempo workouts.

One of Pachev’s preached staples is what he calls his Always On The Run Routine. Basically, after training in the morning, every few hours he will take a break and go jog a mile. Pachev, to paraphrase, says this is to get the body moving, that we as humans were not designed to sit all day and that a short run every few hours is more natural, plus adds running volume and practice.

Keep in mind Pachev at his peak trained 80-100 miles a week, and was capable of running a sub-2:30 marathon. He was an elite-caliber runner and even in his older age probably still is. Even with such a high volume it didn’t take him more 10-12 hours a week to train. So, sure, Pachev’s scheduled short jogs between workouts were probably not too taxing after 10-20 mile workouts in the morning.

That said, though I’m nowhere near the prolific runner Pachev is, I have also taken inter-workout jogs during breaks to generally positive effect. I used to occasionally do them towards the end of my time in Chicago.

And now, I’ve been doing these short jogs during the workday, around the neighborhood during 15 minute breaks and after eating lunch. I had previously walked outside during breaks, but along with wanting to do more than walk I also didn’t like being out in the Vegas sun as long as it took to take these “short walks”. I could finish a jog 5 minutes faster on breaks, and well before the end of my lunch break, without being in the sun long enough to cause distress. Though sun exposure is good for your body, the decreased time in the hot sun was better for my skin.

I’m now running about 3-4 miles during the workday, in addition to training during the morning and weekends (as the heat rises and wanting to get better sleep, I’ve ditched postwork evening runs for now). I have effectively, though somewhat inadvertently, adopted Pachev’s Always On The Run Routine.

And, despite my current weekly mileage rocketing upward from all these little runs, I don’t feel any significant signs of burnout, no issues other than a bit of random soreness here or there, or occasional fatigue accumulation (as you would after a few days of multiple runs).

Plus, my running has shown more substantial week over week improvement than it was during earlier conventional training. I simply took one day off this weekend, and my running improved dramatically once I returned on Monday. Bear in mind that I’m not coming off a break in training: I’ve been running and endurance training for a while.

So obviously this had me considering what about this routine contributes to run development. I did land on a few ideas.

The TB12 Diet Is Really No Big Deal

This morning I saw Pete Blackburn’s CBS Sports writeup about practicing the TB12 Diet for a week.

TB12 is the health and fitness approach of football star Tom Brady, who as you might have heard had led the Tampa Bay Buccaneers to the Super Bowl, which will be played this Sunday. Brady published a book about his approach a short while back.

The TB12 Diet is built around a restrictive diet with the following rules that Blackburn helpfully outlined in his story:

Heart Rate Training Zones: A New Approach

Photo by Torsten Dettlaff on Pexels.com

Heart Rate training zone systems take for granted that a fairly high level of sustained aerobic effort is comfortable or consistently sustainable for most people, which of course it’s not. Most runners just take for granted that it’s normal and never consider that what they consider “easy” or “recovery” is in fact still too hard.

One of the reasons a runner’s aerobic development improves more quickly than their neuromuscular development is because running itself is very demanding. On both fronts you’re being pushed very hard. However, your aerobic and hormonal capacities bounce back much more quickly than your muscles, bones and joints.

Still, it’s incredibly stressful on your body chemistry to go that hard that often, and the fatigue can snowball too quickly for you to be able to handle a high volume of that kind of aerobic training.

In my cross training, I find I need to go pretty hard to get to Zone 1 in most heart rate training zone systems… somewhat too hard for the purposes of whatever cross training I’m doing. The level of effort require would leave me rather tired and possibly sore. This supposed recovery exercise ends up not helping me recover much at all.

It’s not that most runners are just stronger. They just spend all their lives in this perpetual fatigue, physical and adrenal. The long term effects on their health are taken for granted as aging or wear and tear, when in actuality it’s probably preventable… without compromising your fitness or development.

My most recent heart rate zones of choice were a standard 50/60/70/80/90/100 split based on the Karvonen Formula, which uses heart rate reserve. This is a function of your resting and max heart rates, and the zones are proportioned against those rates. Zone 1 for example would be 50-60% of the gap between your resting and max heart rate (your “heart rate reserve (HRR)”), zone 2 60-70% of the HRR, etc.

With a max HR of around 184 beats per minute, this sets my minimum training heart rate around 120 (depending on what my resting heart rate is at that time), with zone 1 peaking at about 130-135. This is about where most heart rate zone systems would put zone 1, and is considered a “recovery” heart rate.

On the spin bike, even at a brisk but easy effort, my heart rate is around 105-110. On the ARC Trainer I can get to 125-130, but only with a more moderate effort. On the rowing machine, a concerted effort typically gets me to about 110-120.

However, when running, I rarely can cruise at a heart rate below 130, no matter how slow and easy I run. I basically have to stop and walk/run to average a zone 1 heart rate. This is not a product of lacking fitness: Even at my peak condition and training in Chicago, it took the right combination of circumstances for me to average 125-130 at an easy effort.


All of this is to say that maybe our view of heart rate zones and “recovery zones” is a bit warped and could use an adjustment.

This is especially true in our coronavirus circumstances, where if we go to the gym (and in many cases train outside) we need to wear a mask while while exercising. We can’t huff and puff at full volume and expect max results if a mask is filtering much of the air taken in or expelled. I’ve talked before about this being a long term training benefit, but in the present it makes the effort required for aerobic training a bit too much.

Bear in mind as well that, to maintain the typical intensity for a full volume of training, you have to consume a lot of carbohydrates, which can cause a variety of inflammatory health problems if consumed in the large amounts that most endurance athletes tend to require.

One of the reasons low-carb diets tend not to work well for endurance athletes is because they train at an intensity where they need a lot of glycogen, and that can only come from and be replenished from a carbohydrate rich diet.

Could it be possible to scale back carb consumption to a more (shall I say) human level, rely more on slower fat burning, and still be able to train, perform, and develop at a high level.

I say yes, and I say the key to doing so is combining (now-)traditional 80/20 training principles with a revised approach to heart rate zones.

Should You Intermittent Fast? A Basic Primer on Intermittent Fasting

Photo by Omar Mahmood on Pexels.com

First, in brief:

Intermittent fasting can work sometimes with exercise, depending on what you do and how.

You should avoid intermittent fasting if you work out in the morning.

The more training you’re doing, the less likely it’s a good idea.

Most of those who practice intermittent fasting and train effectively only strength train as their only meaningful, intense exercise. Generally, their only aerobic training is whatever walking they do during the day, or very brief high intensity interval training… if they do any cardio at all.

If you don’t do much exercise at all, then yes intermittent fasting is a good idea. And you should probably get some exercise, but intermittent fasting is a good habit.

A General Overview of Intermittent Fasting:

Instead of traditional fasting, where you may go a day or more without eating… intermittent fasting is about eating all your day’s meals in a short window of time and not eating the rest of the day.

Even if you eat a similar number of calories, the long break from eating gives your body an extended metabolic break, which can help reduce inflammation and better promote healing and recovery. This is actually more of the benefit of intermittent fasting than the potential fat burning improvements that can occur during the fast.

There’s no calorie restriction on how much you eat during the food window. But, obviously, it’s going to be harder to overeat in a single 8 hour window than it would be if you ate meals throughout the day.

Still, it is possible to outeat the fast during the 8 hour window and still maintain or gain weight. The fast doesn’t cause you to lose weight in itself. While it’s obviously more difficult in a shorter window of time, you can still overeat. That said, intermittent fasting can help with food portion and weight control.
