Wikipedia has the clearest definition of bodyweight exercises. They are those that use the body’s own weight to provide resistance against gravity. Unlike traditional exercises, which involve only one muscle group at a time, bodyweight training works multiple muscle groups at once.
Although it may seem like an impossible task, performing body weight exercises can improve the performance of isolation exercises. As long as they improve as you get better, the more challenging they are, the better the impact on the body. Also, with no equipment to set up or learn, performing bodyweight exercises is ideal for everyone.
With so many variations of body weight exercises to choose from, it’s easy to find something that works for you. If you’re looking for a way to improve your fitness level without breaking the bank, try modifying a move or two.
