Conditioning is an essential part of any fitness programme
Unlike strength training, conditioning sessions involving short periods of intense effort develop your cardiovascular capacity, strengthening your heart and lungs while increasing your metabolic rate.
This, combined with resistance training, whether through weight or body weight training, is a sure way to ensure that you get the results you want in the shortest amount of time.
Of course, 2-3 hours of training can be easily undone with the remaining 165 hours in the week. So, the effort in the kitchen falls to you!
