A trainer who keeps building muscle past age 50 says the secret isn’t lifting heavier every day, it’s walking every single day.
Quick Take
- Trainer John Krahn says he walks daily but doesn’t lift weights every day, using walking as his fallback on busy days
- Krahn favors machines and swaps out painful exercises for alternatives that don’t hurt his joints
- He warms up with sled pushes, recommending two to three sets of 30 seconds, especially before upper-body workouts
- Research backs the core idea that people over 50 can still build real muscle and strength through resistance training
A Trainer’s Daily Routine For Building Muscle After 50
John Krahn, a trainer featured in Men’s Health, shared four habits he uses to keep adding muscle well into his 50s. His approach leans on machines, exercise swaps, sled pushes, and daily walks. Krahn put it simply: “I don’t lift weights every day, but I walk every day.” That line captures his whole philosophy. Consistency beats intensity when the body starts changing with age.
Krahn treats walking as a non-negotiable, even on days packed with meetings or travel. If he only has 15 minutes, he still gets outside and moves. This isn’t about burning calories. It’s about keeping joints loose, blood flowing, and the habit alive on days when a full gym session isn’t possible.
Why Machines And Swapped Exercises Make Sense Later In Life
Krahn prefers machines over free weights for much of his training. A 2024 study found that machine-based resistance training produces real strength and functional improvements in older adults, without needing complicated setups. That lines up with his choice. Machines also let him control range of motion tightly, which matters more once joints start complaining about certain movements.
When an exercise causes pain, Krahn doesn’t push through it. He swaps it for something else that hits the same muscle without the ache. This fits guidance from the National Strength and Conditioning Association, which calls for individualized programs that account for joint stress, soreness, and each person’s tolerance. A 2022 review also found that heavy-load training can be rough on older adults with joint issues, making lower-load alternatives a smarter default.
The Science Behind Building Muscle Decades Later
None of this works if muscle growth stops being possible with age, but it doesn’t. A 2020 review of multiple studies found that even very elderly adults can increase muscle size and strength through resistance training. That’s the foundation under Krahn’s whole routine. Age slows things down, but it doesn’t shut the door on progress, which is good news for anyone who assumed their lifting years were behind them.
Krahn’s fourth tool is the sled push, which he uses mainly as a warm-up before upper-body days. His recommendation: two to three sets of 30-second pushes. Sled work raises heart rate, activates the legs and core, and gets the body primed without loading the joints the way a heavy squat might. It’s a practical bridge between cardio and strength work, especially for someone managing recovery more carefully than they did at 25.
What The Research Doesn’t Settle Yet
Krahn’s approach is built on his own experience, not a formal study of his exact combination of machines, substitutions, sled pushes, and walking. Broader research supports resistance training in general and machine-based training specifically, but no study has tested whether Krahn’s particular mix outperforms other methods for men over 50. That distinction matters. The individual pieces have evidence behind them. The full recipe is one trainer’s personal formula.
That doesn’t make the advice worthless. It makes it a reasonable starting point rather than a prescription. Anyone over 50 chasing strength gains would do well to borrow the underlying principles: train consistently, protect painful joints, and move every day even when lifting isn’t on the schedule. The specifics can be adjusted to fit individual health conditions, which professional guidelines consistently recommend doing anyway.
