This workout is quick, intense, effective, and can easily be done at home if you don't have time to make it to a class. The compound movements burn more calories than isolated exercises and because you're working to your max for about 15 minutes straight, you'll feel the benefits on your metabolic rate throughout the day.
Warm up for 5-8 minutes with a mixture of mobility movements and gentle pulse raising exercises before flowing through the workout below. All you need is a heavy kettlebell and a timer.
Rest for 2 minutes, and then go straight into this 4 minute metabolic set. Complete as many rounds as possible (AMRAP) within the 4 minutes, counting how many times you make it through. Try to match or beat your number the second time around.
