How long should I rest between sets of exercise?
We all have very different goals when it comes to working out, but for most people looking to improve their muscular fitness, it's best to rest for 30 to 90 seconds between sets of an exercise. You should feel energized to get after your next set, but not so relaxed that your heart rate drops and your body cools down.
How long should you take breaks between exercises?

After you reach the absolute minimum, you are ready to start the most intensive type of the training, also called circuit training.
