GET FIT IN 15 MINUTES

WHAT TO DO

LET’S activate those glutes. To tone your bum, try single leg clams, says celebrity personal trainer Nadya Fairweather (u-shape.co.uk). Put a timer on for 45 seconds on repeat. Standing on your left foot and holding a softly bent left knee, bend your right knee, lifting your right foot back, knees in line with each other — so that you look like a flamingo. Slow and steady, lift and lower the right knee without lifting the right hip, isolating the glutes to control the movement. After 45 seconds repeat with the left leg. Try for three rounds on each side. On the fourth round, try lifting and pulsing to get the burn.
