Mr Z

An AI Coach for Men Over 40

What actually changes after 40

Recovery margin shrinks with age. A night of poor sleep or a stretch of low-carb eating that barely registered in your twenties starts showing up directly in performance and body composition by your forties. The fix isn't more training, it's a plan that treats recovery as part of the protocol, not an afterthought.

How Mr Z adjusts for this

Recovery and hormonal efficiency are read first. Where signs of imbalance show up, bloodwork through a trusted provider is the recommended first step before training adjustments. From there, the plan tracks recovery as closely as it tracks training itself, watching for the insulin resistance and cortisol patterns that quietly stall progress in this age group.
