Start every morning with a simple easy gentle and kind warm up. Even a ten or fifteen minute warm up is good often you will want to do more. Always do a simple warm up. Squats do 3 sets of 30, arm rotations 3 sets of 30, pushups 3 sets of ten or more. situps 3 sets of 30. It is a simple exercise of selfdisipline. Once you warm the muscles up, often you will want to do more. Always do a minimum. I admire your maturity and selfawareness you will help alot of young girls learn to stand on their feet, and not allow themselves to be taken advantage of.
