GET 15 FIT IN MINUTES

what to do AS WE age our skin tends to lose elasticity and muscles lose strength and bulk. This can cause droopy skin, especially around the knees — unless you keep muscles strong, advises personal trainer Nadya Fairweather ( u-shape.co.uk).

Focus on the quad muscles at the front of your legs. Try 15 squats, then a brisk walk up and down stairs, a five-minute power walk, then ten walking lunges.

For a walking lunge, start with feet shoulder-width apart, hands on hips. Step forward with one leg, flexing the knees to drop your hips until your back knee nearly touches the ground. Repeat on other leg.
