Jumping jacks are a cardio exercise.
It keeps your heart rate steady, improves blood flow, controls and maintains blood pressure, lowers bad cholesterol, and keeps strokes and heart attacks from happening.
What are jumping jacks?
Jumping jacks are a great, portable total-body workout. This is jump training or plyometrics. Plyometrics combines cardio and strength training. It works on your heart, lungs, and muscles.
jumping jacks work your:
Hip flexors, glutes, quadriceps
Jumping jacks work your abs and shoulders.
What are the benefits?
Plyometric exercises help people run faster and jump higher. Plyometrics work by rapidly stretching and shortening the muscles (concentric phase).
Other examples of plyometric exercises:
- squat jumps
- box jumps
- lunge jumps
Jumping jacks can replace treadmill or stationary bike miles. Jumping jacks move your body out of its normal plane of motion and raise your heart rate.
By taxing the muscles in this way, movement becomes more explosive, gaining strength and agility for multidirectional sports.
Jumping may help bone health. In one study, rats jumped for eight weeks (200 jumps per week compared to 40 jumps per day for five days).
Their bone density increased significantly after jumping compared to the control group. The rats kept their gains even after 24 weeks of training which was only 11% (21 jumps per week) as hard as the first test.
Regular exercise can also benefit:
- weight management.
- reduced blood pressure.
- reduced low-density lipoprotein (LDL) cholesterol, the “bad” cholesterol.
- increased high-density lipoprotein (HDL).
- cholesterol, the “good” cholesterol.
- increased insulin sensitivity.
What about calories burned?
A 150-pound person doing 100 jumping jacks for two minutes burns 19 calories. 10 minutes of jumping jacks per day burns 94 calories.
Are there any risks?
Jumping jacks and other plyometric exercises can injure the knee and ankle. As with most exercises, the risk is higher without a strong base.
Consult your doctor before starting a program if you have joint or muscle issues.
Jumping jacks are safe for most people. This includes young and older athletes.
Jumping jacks and pregnancy
In all trimesters of pregnancy, ACOG recommends 20 to 30 minutes of moderate-intensity activity. The ACOG says exercise helps maintain fitness, weight, and gestational diabetes risk.
The ACOG doesn’t say to do jumping jacks, but they recommend “low-impact” aerobics over high-impact sports like gymnastics. Consult your doctor about safe exercise during each trimester.
If you had an uncomplicated pregnancy and regularly did jumping jacks before becoming pregnant, consult your doctor. Pregnancy affects your joints and balance.
With a doctor’s OK, some women can exercise vigorously until delivery. Second and third-trimester exercises must be approved.
Pay attention to your body and adjust based on complications and your doctor’s advice.
