Training After 40: Strength That Lasts from CrossFit BC. A coach's guide to strength training after 40: the science, the four lifts that matter most, and a weekly template you can run for thirty years.
Training After 40: The Science of Building Strength That Lasts
This article is part of the CrossFit BC journal, written by the coaching staff who run our classes in Olympic Village, Vancouver. We publish what we teach on the floor: training decisions, recovery, nutrition, and the honest tradeoffs behind them.
Yes, when you are coached properly and progress load over time. The published research consistently shows resistance training is one of the safest and highest-return interventions for adults at every age tested, including into the 70s and 80s. The risk is not lifting heavy. The risk is staying weak.
Two well-coached strength sessions per week is enough to drive meaningful adaptation for most adults. The CrossFit BC template is squat focus on day one, hinge focus on day two, with optional aerobic work on the other days.
You will get stronger on machines, but you will leave the biggest payoffs on the table. Compound lifts like squats and deadlifts drive bone density, posterior chain strength, and whole-body coordination in ways machines cannot replicate. Coached barbell work is the gold standard for healthspan.
Coached lifting at appropriate load does not cause arthritis. The evidence actually points the other way. Loaded movement maintains cartilage health and joint function. Most lifting injuries in older adults come from poor coaching, ego loading, or skipping warm-ups. None of those are inevitable.
For active adults over 40, the research suggests 1.6 to 2 grams of protein per kilogram of bodyweight per day, spread across three or four meals. This supports muscle protein synthesis and helps offset the natural decline in anabolic response that comes with age.
Yes. Studies on adults starting resistance training in their 60s, 70s, and even 90s show meaningful gains in strength and muscle mass within 12 to 16 weeks. The body responds to a real stimulus at every age.
Yes, but you do not need much. Two zone 2 sessions of 30 to 60 minutes per week (conversational pace walking, biking, or rowing) is enough to maintain aerobic capacity alongside strength work. Strength is the foundation. Cardio is the complement.
Yes. The largest single demographic at CFBC is adults from 35 to 65 who train two to four days per week and want to be strong, fit, and moving well in their 70s. We have a Foundations program designed specifically to teach the four lifts safely, and coaches who specialize in long-term training for adults.
