If you're used to doing
high intensity circuit training, kettlebell exercises can be a great addition for getting your heart rate up and burning more calories.
In a study done recently, referring the effectiveness
of high intensity circuit training, published by the American College of Sports Medicine, the researchers designed a conditioning routine that can be done anywhere in a little less than 10 minutes.
I'm a 23 yr old, 173 cm, 70 kg mesomorph who has been doing
high intensity circuits with a combination of weights / body weights 3 - 4 times a week and a HIIT session, approx duration of 30 - 45 min.
Using your own body weight,
high intensity circuit training (HICT) burns maximum fat by using resistance training while working multiple large muscles with minimal rest between sets keeps metabolism high for up to 72 hours and also increases VO2max.
