Too busy to exercise? This is easy to understand, especially if you are trying to follow the exercise instructions, which involve an hour a day most days of the week. However, experts have found that short workouts, such as two or three 10-minute workouts a day, can be just as effective as longer workouts. The main thing is to focus on intensity and use your time wisely. So how do you add intensity to your workouts? Try active activities such as Jogging, jumping rope, or plyometrics . If a strong shock load isn't for you, you can get a great workout with low-load exercises . The point is to try compound movements to work more than one muscle group, otherwise if you do cardio exercises with a low load, the speed and range of movement will definitely increase your heart rate.
