Isolation exercises are designed to target how many muscle groups?

Isolation exercises are specifically designed to target a single muscle group at a time. This focused approach allows for greater activation and fatigue of that particular muscle, which can be beneficial for strength training, muscle hypertrophy, and rehabilitation purposes. For example, an exercise like the bicep curl targets only the biceps, thereby helping to improve the strength and size of that specific muscle. This differs from compound exercises, which engage multiple muscle groups simultaneously. By isolating a muscle, trainers can also address strength imbalances and concentrate on form and technique. Consequently, the objective of isolation exercises is to enhance the performance, appearance, or recovery of one specific area, making targeting a single muscle group their fundamental characteristic.
