Here’s a stat that should bother you: after 40, your body quietly sheds about 1% of its muscle mass every year.
No warning. No alarm. Just a slow fade — like a savings account with a tiny monthly fee you never noticed until the balance looks wrong.
By 50, you’ve lost roughly 10% of the muscle you had at 40. By 60, you’re negotiating with gravity every time you stand up from a low chair.
The good news? Muscle responds to resistance training at any age. You don’t need to live in the gym. You need to show up with a plan.
Move 1: Body — Do 3 sets of goblet squats, 2x per week.
One exercise. Hits your quads, glutes, and core. Use a dumbbell or kettlebell you can handle for 10 clean reps. This is the compound interest of strength training — boring per session, transformative per year.
Move 2: Fuel — Hit 1 gram of protein per pound of your goal body weight. Every day.
Most guys over 40 are eating half the protein they need (or less). Your muscles can’t rebuild with what you’re not giving them. Think of protein like building materials — you can’t renovate a house with a bag of nails. Build every meal and snack around it. Track it (you’ll be surprised).
Move 3: Mind — Track your lifts in a notes app or Google sheet. Just the weight and reps.
What gets measured gets managed. You don’t need a fancy app. You need to know if last week’s goblet squat was 35 lbs or 40. Progress is the signal that tells your body to keep building. Try to add 2.5 – 5lbs per week. Every 5th week, do half the weight to let your body recover.
The takeaway: You’re not too old to build muscle. You’re just too late if you never start.
Forward this to a dad who used to be strong. He still can be.
