In a previous blog I discussed the importance of training within the movement categories. Those categories are upper body push and pull, squat, and hinge. To break it down even further within the categories, there are exercises that give you more bang for the buck than others. In this blog I differentiate between compound and isolation exercises. For those of you who are on a time crunch when you are in the gym, these exercises are crucial to get the most out of your training.
What Is the Difference?
A compound exercise is also known as a multi-joint exercise. This is an exercise in which more than one joint is required to move through the exercise. An example of a compound exercise would be a squat. To complete the squat pattern, three joints must move: the ankle, knee, and hip. Examples of compound exercises for the upper body are the bench press and overhead press. Both movements require the function of the shoulder and elbow. The reason that compound lifts have more payoff is that they work multiple muscle groups as well. A bench press uses the pectoralis muscles, deltoids, and triceps. This requires more energy to be expended than if you used only one of those muscle groups on a single joint exercise. Exercises that isolate a single muscle group are called isolation exercises. Examples of an isolation movement would be a bicep curl, triceps extension, leg extension, or a leg curl. The difference between a compound exercise and an isolation exercise is the number of joints that move.
Which Type of Exercise Should You Do?
Compound lifts are more challenging but less time consuming than performing multiple different isolation exercises. If you short on time while in the gym, a full-body workout full of compound movements will give you the most from your workout. I have written blogs about how to structure those types of workouts. If you want to sculpt your body in a particular way, and are focused on correcting muscle imbalances or injury rehabilitation, each may require the use of specific isolation movements to build up specific muscle groups. So, the question is, what are your goals? Once you define your goals, you can design your workout program.
Structuring a Workout
The most efficient way to structure a workout utilizing both methods is to perform a compound movement first in your workout followed by isolation movements to complement the muscles used in the compound movement. A quick example using the bench press would be bench pressing first, followed by isolation movements to isolate the chest and triceps. You want to save the most amount of energy for your compound exercises, which is why you should perform this one first. Fatiguing the triceps before a heavy bench workout will not yield the best results for bench press. This is why isolation exercises are best performed at the end of your workout.
