Muscle-strengthening activities improve the strength, power, and endurance of your muscles. Examples of muscle-strengthening activities are: 1  doing pushups and situps. 2  lifting weights. 3  climbing stairs. 4  digging in the garden.
Powerlifting consists of three primary exercises -- the squat, bench press and deadlift, in which lifters compete to see who can lift the most weight on each. In a competition, you have three attempts at each lift, and the highest score on each lift is taken and added together to make your total.
