5 Rep Ranges You MUST Know for Hypertrophy After 40 (Andy Baker)

If 5 to 30 reps can all build muscle, why do some rep ranges clearly work better than others? 

After 40, could the “science-based” advice you’re following be the exact reason your progress has stalled?

I brought strength coach Andy Baker back to challenge one of the most oversimplified ideas in evidence-based fitness: that rep ranges are basically interchangeable.

We break down the five rep ranges you need to understand, from heavy 1 to 4 rep strength work through 20 to 30 rep sets, and exactly where each belongs in your training.

You’ll learn why 4 to 8 reps may be the “meat and potatoes” for getting brutally strong and building muscle, when higher reps make more sense for isolation work and cranky joints, and why the effective reps model gets misunderstood.

Plus, Andy shares his simple 80 percent rule for programming your lifting weights after 40.
