A drop set is an advanced resistance training technique used in bodybuilding and weight training to continue an exercise with a lower weight once muscle failure has been achieved at a higher weight. The goal of a drop set is to gain more muscle than you would doing conventional sets. The technique involves completing a set of a given exercise until failure, then immediately reducing the weight or resistance by 10 to 30% and beginning another set. This process can be repeated multiple times, with the weight being reduced each time, until the muscle is fully fatigued. Drop sets are an effective way to promote muscle hypertrophy, or gains in muscle size, and muscular endurance. They can also help save time in a workout due to minimal rest involved. However, drop sets should not be incorporated into every set or too frequently in a training regimen to prevent overtraining.
