If you would like to cut down your time in the gym and still get great results from your workout, you should try high intensity weight training. This training is supposed to give you excellent results in only 15 minutes a week, but be prepared – this workout is brutal! This training is not new. Arthur Jones introduced this strenuous workout in the 1970’s. He is the inventor of the Nautilus workout machines, which were highly popular during that period. His theory of working out is to work fast, furious, and then allow the body time to recuperate.

This high intensity type of workout is said to build your muscles faster than conventional workouts. A resurgence in this workout began in 2008 when the book Body by Science was published, which was written by Doug McGruff, M.D., along with John Little. They give a fresh view on the theories of high intensity workouts along with scientific evidence that it works and why.

There are some vital points that you need to know in order to include high intensity workouts in your training. First, you will use very heavy weights to exhaust your muscles in less time. You will also remember to only work out for a short time, ultimately 15 minutes. Make very controlled movements when doing reps to make muscles extremely fatigued, and allow time for recovery, which is suggested to be 3, 4, or even 7 days. At no time should you extend this type of workout over 40 minutes, no matter how great of shape you are in.

That’s it! This almost sounds too good to be true, but it is again becoming popular. Even sprinter trainers are including this workout to gain muscle strength and endurance. Using lower reps along with heavier weights, working your muscles to total fatigue while using proper form, and having a short workout, all backed up by scientific evidence, make this is a workout plan that we should all revisit.
