This week's #MondayMove is, 'a great stability move to work the butt (glutes) that also focuses on the hips, lower back and core,' explains Anya Lahiri, trainer at Barry's Bootcamp London.
Start on your hands and knees and with your palms flat on the ground and your knees bent
Keep your elbows locked out and your arms straight
Relax your core and keep your back neutral
Raise your right knee out to 90 degrees (it may not go this high but go as high as you can without the posture of your back changing)
Squeeze at the top and then return to start position
REPEAT for 30 seconds on one side and then go for 30 seconds on the other side.
