Workout Description

Power 8 is a muscle building workout system that attacks major muscle groups in 3 different ways:

  • Power - Each major muscle group is first hit with a ramping 5x5; the same style of 5x5 made famous by classic bodybuilder Reg Park.
  • 8x8 - Following the power sets, major muscle groups are then taxed using an 8x8 protocol. Rest between each of these sets is kept to 60 seconds maximum.
  • Isolation - Major muscle groups are "finished off" using an isolation exercise that focuses on a strict rep cadence.

Smaller muscle group are worked in a similar manner, but do not contain power movements. In addition, instead of performing an 8x8, you will target minor muscle groups with a 6x8 before finishing them off with an isolation movement.

  • 6x8 - Minor muscle groups are first targeted with an 6x8 protocol (6 sets x 8 reps). Rest between each of these sets is kept to 60 seconds maximum.
  • Isolation - Minor muscle groups are "finished off" using an isolation exercise that focuses on a strict rep cadence.

Power 8 - Three Day Split

This 3 day split should be performed with at least one day of rest between workouts, if possible. You can rotate this 3 day split over the course of 6 or 7 days.

7 Day Variation

  • Day 1 - Chest and Back
  • Day 2 - Off
  • Day 3 - Leg and Abs
  • Day 4 - Off
  • Day 5 - Shoulders and Arms
  • Day 6 - Off
  • Day 7 - Off

For the 6 day variation, simply do away with "day 7" and start the rotation over again. If your schedule forces you to workout 2 days in a row, the following schedule is recommended.

7 Day Variation - Back to Back Variation

  • Day 1 - Chest and Back
  • Day 2 - Leg and Abs
  • Day 3 - Off
  • Day 4 - Off
  • Day 5 - Shoulders and Arms
  • Day 6 - Off
  • Day 7 - Off

You want to keep rest between pushing days (chest - shoulders and arms) to a maximum. Keep those days in the same place, and adjust your leg training day as needed.

Selecting Exercises

Don't shy away from hard exercises. If you do, you're only selling your results short. A sample template is included below. If you need to change exercises because of limited equipment, choose the best possible substitutions. Try to make equal exercise swaps. Power 8 is set up as follows:

Major Muscle Groups
  • Power - A 5x5 using a heavy compound lift.
  • 8x8 - An 8x8 using a less impactful heavy compound movement, or a machine exercise.
  • Isolation - A 3x8-12 using an isolation style movement.
Minor Muscle Groups
  • 6x8 - A 6x8 using a challenging isolation or machine exercise.
  • Isolation - A 3x8-12 using an isolation style movement.

As mentioned, 5x5 exercises are ramped. The first 2 sets are working warm up sets.

  • Set 1 - 60% x 5 reps
  • Set 2 - 80% x 5 reps
  • Sets 3-5 - 100% x 5 reps

Set 5 is an AMAP set, meaning you will perform as many reps as possible. Do NOT train to failure. Stop set 5 when you feel like you might fail on the next rep, or if your form starts to severely deteriorate. When you reach 7 or more reps on set 5, it is time to add weight. The next time you hit the gym, add 5 pounds to the bar.

8x8 and 6x8 Exercises

Rest between sets for these exercises is kept to a strict 60 seconds. Do not exceed this rest period. If you are unable to hit 8 reps for each set, don't worry. When you are able to perform 8 reps for each of these sets, it's time to add weight to the bar. Add the smallest possible amount of weight the next time you perform this movement.

Isolation Exercises

Perform these movements using a 4-2-4 rep tempo. This means it will take you 4 seconds to compete a rep, followed by a 2 second hold at the point of contraction, and a 4 second eccentric - or returning of the weight to the starting position of the exercise. Add weight when it makes sense for these exercises.

There is no need to force heavier weights before you are ready. Also, you may need to drop weight from set to set. These exercises are very deliberate and taxing. Dropping to a lighter weight is perfectly fine. Again, the point is to finish off your muscles, so weight used is secondary. With that said, don't go "too light", this making a set too easy.

Power 8 - Frequently Asked Questions

When can I work abs?

You could add in 3 sets per day after each workout. Use whichever exercises you prefer.

Can I add in deadlifts?

Yes, you can use deadlifts on back day for your 5x5 exercise. If you do this make sure to use some form of row and pull up/lat pull down for your next 2 exercises. You may want to rotate weeks, and do an 8x8 for rows one week, and an 8x8 for pull downs or pull ups the next.

What about forearms?

You really shouldn't need to work the forearms directly in the context of this system. Your forearms will receive plenty of quality stimulation.

Can I add in more arm work?

No. Trust the process. This workout system will build plenty of arm size.

Can I add in more chest work?

No. Trust the process. This workout system will build plenty of chest size.

I started this workout 2 weeks ago. I only have 3 days to go to the gym, and also have herniated disc. I came back to the gym last year, but was getting boring with always the same way of doing exercises, reps and weights.
This new plan, is giving me an additional motivation in the morning (I workout at 6am..), and have good feeling.
I will probably go for a 3-days full body workout after the 8 weeks of this one.
Thanks to BB for the ideas!
Cheers from Madrid

I am fairly new to lifting just started this routine 2 days ago and will be doing legs today. I will be doing the 6 day cycle. When I start the cycle over and go back to chest and back how much of a change do I need to make to the types of lifts I am doing? Or can I keep them the same each week? I am having trouble getting a plan together for the weeks to come because I am still failry new at this and I don't know what would be good lifts. If there's anywhere I can pay for someone to put together a workout plan for me any recommendations would be appreciated. Or simply a nudge in the right direction on what workouts to do each week.

Hello

I also have a question about the weight % 60; 80. Is it of 1RM max or the weight you are using for working sets?

This workout looks great but I see it is a once per week program. How effective is once a week? According to science it is not as effectice as twice a week.

Hi Orly,

It's still effective and more so than 0 times per week. A lot of people see great results hitting muscle groups once per week. The science doesn't factor in enjoyment level which leads to consistency. And consistency at the end of the day is the main driver of progress.

Hope this helps!

Hi Pabir,

Body types is a dated theory. This workout will help you build muscle when performed in conjunction with a solid diet and adequate sleep each night.

Hi!
I have a question regarding volume. So I would do #1 exercise for 5x5 then #1 exercise for 8x8 and then #1 exercise for isolation? For a total of three exercises. Am I correct?

Also for back, would I do deadlift 5x5 and then chest 5x5? Is that it?

Thanks

I'm not very good at pull ups yet so I am using a resistance band at my feet to help me get through all those reps. I was wondering if I should stick to one grip through all 8 sets or if it okay to change it up.

Great workout, how could I go about turning this into a push, pull, legs program? I just prefer working chest shoudlers triceps, back biceps, and legs on their own

How would you go including bodyweight progression into this training?
I'd like to improve a bit on my pullups/pushups and eventually try go for a muscle up and a human flag
I also love forearm work, farmer walks, leverring, how would you implement those ? thanks :)

I really like this workout, but.. I am concerned about the the time in the gym as I can only really go during my lunchtimes at work.

I was previously doing the bulldozer workout (again isnt this a Steve Shaw workout) which was 7 exercises. I was pushed for time but manage to do it, whereas this one looks like it may take me longer.

I suppose I should not cut out any of the exercises here ?

I'm going to start doing this workout split. I'm getting married in six months and would like to put on some muscle and drop body fat. Would it be overkill to do some HIIT cardio 1x2 a week on a non-lifting days to help cut down some fat since I'm in a time crunch to get ready for the wedding??
Thanks,

I like this workout--I'm looking to build mass over the next six months; I've been working out consistently for years but looking to up my game. I wanted to alternate the three days with CrossFit WODs. Is that a good idea? That would give me one day of rest (or maybe yoga?) a week.

Hey, I'm a flat roofer and work pretty hard. Even with a 2500-3000 calorie diet I lost 10 pounds in 5 weeks. I'm 25, 5'11 and weigh 190. I want to put on some heavy lean mass. Would you recommend this plan or another plan? I am currently taking 2 scoops of mutant mass plus vegegreens in the morning before work and after any workout that I'm able to squeeze in. I also take bcaas to work and during my workouts. Are there any other supplements I should be taking?
ps; I don't take a multi, my minerals and vitamins are all in my food.

I've been doing the workout for 3-4 weeks and love it, but I am finding that doing chest and back the same day is nearly impossible. For one thing, it makes for a 70-minute workout. For another, I am nearly wiped out from just doing chest and then I do 5x5 deadlift. At that point, I am usually totally wiped. Am I kind of kidding myself with doing chest and back the same day? Does this need to be a four-day split with chest one day and back on another?

I have a quick question. When you say that if I want to add deadlifts that i should make my next 2 exercises a row and pull up, does that mean do an 8x8 or 6x8 for each of those and then do the pull downs and shrugs?

Hi there, I've been training for about 3 years now with a few months out last year, thanks to studying mainly for limiting gym time. Currently doing A levels so can't spend more than about 3 evening a week in the gym, possibly one extra at the weekend (usually Sunday) if I have the opportunity, and I tend to use this for the 100 reps workout you wrote about. Specialised nutrition is something that is largely beyond my budget, plus I don't mind having slower results as gym is an excellent stress reliever for me and I really enjoy it, I just do my best to compensate by eating as much meat and fish as possible and I have eggs of some form usually every morning. Combining this with a 30 minute run 5 days a week, what kinda results should I expect and in what time frame? Should I maybe go for a different workout and try and adjust my schedule or will this be suitable?
