Are bodyweight/air squats cardio?
While you can probably rep out dozens of bodyweight squats or air squats, this is still not considered a cardio exercise. However, you could use them as part of a circuit training program to burn calories and fat while improving general fitness.
Are jump squats cardio?
Jump squats are essentially a step up in difficulty from bodyweight squats. Therefore, you probably can’t sustain this exercise for any significant time. As such, jump squats are not considered cardio.
Again though, you could include this exercise in a circuit training program to burn fat and improve fitness.
Will squats improve my cardiovascular fitness?
Heavy squats for 8-12 reps with shorter rest periods can increase your anaerobic threshold. In other words, you get better at sustaining exercise at 80-85% of your max heart rate.
However, squats do not improve your cardiovascular fitness in the aerobic range or 60-80% of your max heart rate. So if you only do squats, you will be out of breath quickly when you go for a jog.
Do squats burn belly fat or thigh fat?
Squats burn calories, and some of those calories come from fat. But it’s important to realize that squats do not “spot reduce” body fat from specific body parts like the belly or thighs.
Instead, squats help you burn more calories to create the overall calorie deficit necessary to lose weight and fat all over your body.
