I have been doing Caroline Girvan programmes for around a year now and have experienced big improvements in upper body and leg strength and these areas are more defined/solid. However my glutes still seem really saggy. I have been using 30kg for hip thrusts which is the heaviest weight I have and it does not seem to be doing anything.
I am wondering if people have any recommendations of what I can do at home to tone the under butt area? I would rather not join a gym.
