You Don't Need a Calorie Surplus to Build Muscle Over 40

You don't need a calorie surplus to build muscle after 40.

The common surplus numbers are shakier than most people realize. I break down the real energy cost of muscle, what the research says about maintenance versus surplus, and how to tell whether body recomposition is the right approach for you.

I'm breaking down the real energy cost of building a pound of muscle and the 3 conditions that decide whether body recomposition works for you. You'll also hear where the anti-surplus crowd oversells the evidence, why one widely cited recomp study never reported the numbers people claim, and what happened in a study where postmenopausal women lifted for 24 weeks.

If you want to add muscle at the weight you're at right now, hit play!

Learn about:

  • Why fat calories math does not apply to muscle tissue

  • What the Helms 2023 maintenance vs surplus study actually found 

  • What deficit research suggests about the point where lean gains stall 

  • How body recomp gets overstated from studies

  • Why scale weight is a weak signal during recomp and what to track instead

  • 3 conditions that predict recomp success

  • The 2 biggest trade-offs with body recomp
