A BODYPUMP (tm) class is similar to a high-intensity endurance session since it comprises of high repetitions of exercises with very little recovery. A more targeted weight-training regimen may be more beneficial if you want to attain major hypertrophy (muscle development) or strength increases. Weight training can also help prevent muscle loss that often occurs during bodybuilding competitions. There are two types of bodyweight exercises: isolation exercises and compound exercises. Isolation exercises target one specific muscle group while compound exercises work several muscle groups at the same time. Isolation exercises are useful for building muscle definition while compound exercises are best for gaining mass. Both types of exercise are important for attaining optimal fitness. Bodyweight exercises are useful because they require very few equipment needs or costs. You don't need any special tools other than your own body to do these exercises. This means that you can practice them anywhere, even in public places. Moreover, there's no risk of injury from using bodyweight exercises. You won't hurt yourself no matter how hard you push yourself during workouts. However, this kind of exercise is not suitable for everyone because you cannot adjust the resistance levels of these exercises. For example, you cannot perform a set of ten chinups but instead must perform a set of five then rest before repeating the process once more. Finally, bodyweight exercises are fun!
