Overview
- Experts reiterated on Monday that resistance training after age 40 is a key step to slow sarcopenia, keep mobility and sustain everyday independence.
- A British Journal of Sports Medicine cohort of about 147,000 adults found 90–119 minutes of strength work per week was linked to lower all‑cause death and reduced cardiovascular and neurological mortality.
- Practical advice from trainers and clinicians calls for two to three structured strength sessions weekly focused on multi‑joint moves such as squats, push and pull patterns, deadlifts and stability or carrying exercises.
- A small Sleep Science trial of 36 untrained men over five weeks reported similar short‑term arm strength gains for participants sleeping roughly six versus seven hours, but the study's brief duration, small sample and light resistance limit what it proves.
- Exercise scientists warn that chronic short sleep under seven hours and poor sleep quality can disrupt hormones, raise inflammation, impair recovery and reduce the long‑term benefits of strength training.
