In perimenopause, it's not just muscle mass you're losing. It's muscle quality. Declining estrogen creates a disconnect in your contractile proteins that prevents strong, powerful contractions, which is why your pace is slowing and your lifts feel harder despite consistent training. The fix isn't more cardio. It's putting more load on the muscle to teach it to contract powerfully again, which also protects your bones.
Dr. Tracey Clissold is a New Zealand-based researcher and educator with 30+ years in exercise science and sports nutrition. She holds a PhD from AUT University, where her research proved that a targeted jump-landing program can improve bone mineral density by 3.5–5% in just 12 months. She created the OSTEO-GAINS app — a science-backed, 2–5 minute daily bone-building program with over 25,000 users worldwide
