20 min must try HIT workout

Don’t have the time to visit the gym? We have the ultimate 20 min workout that will have you sweating.  You may not feel 20 minutes is enough but short HIIT has been proven more effective than steady-state aerobic exercise (like jogging). HIIT may also be more effective than weight training alone, at the very least from a time standpoint.
This is largely because HIIT challenges both your cardiorespiratory fitness and your musculoskeletal fitness, bringing about improvements to your heart, lungs, muscles and nervous system.
