Building Strength After 40: Programming for the Long Game

Building Strength After 40: Programming for the Long Game

Plenty of our Del Mar and Encinitas clients started training seriously in their forties and
fifties — and made some of the best progress of their lives. Strength training after 40 isn’t
a watered-down version of your twenties; it’s a more intelligent one. Here’s how we program it.

The case for lifting after 40

Adults lose muscle mass and power with age — a process called sarcopenia — and resistance
training is the most effective intervention against it. The ACSM’s position is unambiguous:
strength training preserves muscle, bone density, and functional independence as we age. The
goal isn’t vanity; it’s staying strong enough to do everything you want for decades.

What changes in the program

  • Longer warm-ups. We spend more time preparing joints and tissue before loading them — five to ten focused minutes, not a token stretch.
  • Smarter exercise selection. We choose variations your joints tolerate well — trap-bar deadlifts over straight-bar, for example — rather than forcing a textbook lift.
  • Managed intensity. Heavy work is valuable and safe when programmed correctly, but we leave a rep or two in reserve more often than we would with a 25-year-old.
  • Protein and recovery emphasis. Protein needs trend slightly higher with age; we typically target the upper end of 0.7–1.0 g/lb of target bodyweight.

What stays the same

The fundamentals don’t change with age: train the major movement patterns, apply progressive
overload, and be consistent. A 50-year-old still gets stronger by adding load to a squat over
time — we just manage the path more carefully.

Strength is a longevity investment

Grip strength, leg power, and the ability to get off the floor are among the best-studied
predictors of healthy aging. Every session you put in now is deposited into that account. That’s
the long game we coach toward at Legacy Del Mar — strength that still serves you at 70.
