It involves overcoming the resistance caused by the weight of another object or a force. Resistance can come from free weights, hydraulic machines, rubberized machines, or your body weight. There are three types of categories for resistance training which include loads, repetitions, and sets. Loads are the weight or force being overcome or moved. Repetitions are the number of times you repeatedly overcome the resistance without resting. Sets are the groups of repetitions separated by a rest period of 30 seconds to 3 minutes. .
