Are squats anaerobic or aerobic

Squats can be both Aerobic & Anaerobic but it depends on the speed and duration. Any activity done fast enough with a duration of 2 to 3 minutes is Anaerobic. Beyond the 2 - 3 minutes limit is aerobic. The faster you do it the more burnout you will feel and lactic acid will go to the roof. A good Anaerobic Squats exercise is doing as many as you can as fast as you can with a medicine ball of your desired weight. That will put your pulse to almost 200 bpm or more depending of many factors.
