Challenge #4
What is Plyometrics?
“How many times a week should I do a plyometric workout?“
- This form of exercise should not be performed every day because your muscles need to recover from the intense high impact exercise. A 48-hour rest period between plyometric circuits is recommended. Plyometric exercises are not recommended for novice exercisers, or individuals returning to exercise after a long recovery period. A stable aerobic base and solid core foundation is required to progress to this power level of fitness.
“Can I modify plyometric exercises with low-impact moves?”
- Yes! However, you will not receive the benefits of a plyometric workout. If you regress the exercise, you will still engage in a great workout; it simply will not be plyometrics. Never hesitate to regress a plyometric exercise and perform a low-impact version instead; it is better to begin this power level slowly, focusing closely on form and posture, and recover as needed.
“I’m confused! Are plyometrics strength or cardio?”
- Plyometrics predominantly build strength, however they also incorporate anaerobic interval training, any exercise that does not require oxygen. High intensity interval training is an effective way to improve cardiovascular activity and to quickly meet your fitness goals.
