A great glute-strengthening exercise that particularly benefits desk-bound lower backs; it will also improve hip mobility, which can get too tight when you’re sitting for too long. I use it at the beginning of my yoga classes to prepare the hamstrings and glutes for the yoga practice ahead: it’s low-impact, but if you’re doing it properly you will feel the burn.
a) Come to lie on your back with your feet flat on the ground and hip distance apart. Tuck in your chin and your tailbone.
b) Drive into your feet and lift your hips off the floor; only lift as high as your mobility allows without arching your lower spine (this is not a yoga bridge pose).
c) Repeat three sets for 20-30 reps.
