Strength training is one of the most effective “bang for your buck” habits for heart health — and UK national guidelines recommend muscle-strengthening activities at least twice per week. This post gives a simple plan that works: 2 x 20-minute sessions with warm-up/cool-down, safe intensity guidance (talk test + Borg RPE), and clear progressions so you build strength without overdoing it. Ideal for beginners, returners, and anyone who wants a routine that actually sticks.
