Layne Norton PHAT Workout: Gain Size & Strength At The Same Time

The Layne Norton PHAT workout, which has become quite a famous workout routine is called “PHAT”. The routine was designed by Dr. Layne Norton, physique coach and professional bodybuilder.

Layne designed his program for increasing strength and size at the same time – and he did a great job.

Layne Norton’s workout routine consists of 2 strength training days where you’ll be training with heavy weight and 3 hypertrophy days for stimulating muscle growth. On the hypertrophy days you’ll be using lighter weight, but higher of reps.

The idea is simple, you build up your strength by lifting heavy for low reps, and then you build your muscles up by using higher reps. As you get stronger you’ll be able to use heavier weights for higher reps on your hypertrophy days.




I’ve used Layne Norton’s workout many times over the years and I highly recommend it.

Layne has  done a good job of programming all rep ranges into his workout routine, which is great because each workout you’ll be hitting different types of muscle fibers and stimulating muscle growth every way possible.

Another great thing about the PHAT workout is that it calls for each muscle to be trained twice per week. In my opinion, too many people follow the traditional bro split workout routines where you only train each muscle once per weak.

If you want to build something, you don’t work on it once per week.

Layne Norton Workout, What You Need To Know:

  • It’s only a template – You can and should make changes.
  • Layne’s original routine has ‘speed sets’ programmed into the hypertrophy days. They didn’t do much for me, I noticed better progress swapping them out for 4 regular sets of 8-12 reps.
  • I swapped out ‘Rack Chins’ for more sets of pull-ups.
  • Ditch hack squats for more regular squats or front squats.
  • Rotate bicep and triceps exercises to your liking.
  • Rotate between barbell press and dumbbell press on upper body and shoulder days
  • Swap out squats for dead-lifts every 2-3 weeks on your lower body days.
  • Keep a journal, it’s the easiest way to make sure you’re making progress. I turned this post into a printable workout log. Download it below and take it to the gym with you.

  1. Great stuff, i like the modifications (hack-squats and rackchins out).

    In General, would you say that this System is one that you can do “forever” so that you dont have to think every 8 weeks what program to do next?
