Celebrity trainer Louisa Drake and founder of Louisa Drake Method (LDM) loves using the LDM mini stability ball (£10) in the studio and at home. "I love the mini stability ball as it is so versatile. It can be used to aid a number of exercises, for the core and lower body in particular. It doesn't take up too much storage space at home, and it's nice and portable — you can easily pop one into your workout bag."
"By performing exercises on or with the ball, you can boost muscle compared to without the ball," Louisa added. "In particular, activation of the abdominal muscles is encouraged by crunches on a stability ball, and it is ideal for support after injury, because it reduces muscle and spinal strain for certain movements."
