Six-Minute Chair Circuit Rebuilds Core Strength After 60

Experts say a six-minute chair circuit can rebuild core strength after 60, potentially outperforming planks for older adults by targeting the deep core while reducing wrist and back strain; the routine uses six 45-second moves (seated cat-cow, seated march, torso twist, side bends, knee-to-elbow cross-body, and a V-sit hold) with 15-second rests, all performed in a sturdy armless chair to boost posture, mobility, and circulation.
