ways of exercise minus the gym -
use the stairs instead of the lift, uses alot of calories and helps build leg strength.
at home do press ups and squats (working the legs is a great way of getting in shape, they are a big muscle so working them also burns more calories - working the legs is hard work though which is why I dont do it much )
stay away from bicep curls, they are mostly pointless for stength training etc (good for looking 'buff' if you like that sort of thing )
