Curl Up and Pike is an advanced exercise performed with the fit ball. But, if you don't have all the equipment or if you don't feel confident doing this exercise, you can start with a pair of socks. This way you will strengthen the muscles of the core, back and arms and when you gain confidence you can do it with the ball. Moreover, PBT is great for training in tight spaces and staying active at home. 🏠 #pbtathome #curlandpike #progressingballettechnique | Progressing Ballet Technique
