There are several effective weight lifting exercises that can be done at home without equipment, including using stairs for leg workouts, lying on your side and lifting legs for leg exercises, and pushups to train the chest and triceps. Additional exercises recommended are squats, side lifts for obliques, planks and leg raises for abs, pull ups and bent rows for the back, and stretches to warm up and prevent injury. Always check with a doctor before starting a new exercise routine.
