HIGH KNEES

Basically, this is jogging on the spot but with your knees lifted higher.

SQUATS

Wonderful for legs and glutes. With feet hip-width apart, toes forward, press through your heels and lower your hips towards the floor. Pause for a nanosecond, then come back up.

PRONE LAT PULL-DOWNS

Lie flat on the floor face down, arms straight. Exhale, lift your upper body off the floor and bring your elbows to your waist in a W shape, squeezing glutes to protect your lower back. This works the back and improves posture. Do 10-15 reps at a time.

PRESS-UPS

These are brilliant for arms, chest and core. With knees on the floor, ensure your arms point diagonally behind you and aim your head beyond your fingers. Lower yourself slowly, pause, then push the floor away to come up. Try five repetitions, rest, then maybe try another five.

WALKING PLANK

Get into a plank position on your forearms (with your knees either on or off the floor). Slowly bring yourself up onto straight arms, then come back down to your forearms. This is great for your shoulders and core.
