Intensity is what’s important in this circuit as it uses your cardio-vascular and your lactic acid system in tandem, to achieve an effective functional workout in 45 minutes or less.
This works on a basis of 12-12-12 with no rest between exercises. After you have completed all three exercises, give yourself a 60 second rest break and then get back to it again. You should repeat this five times for best results. If you start to fatigue after the first few sets then increase the rest time to 120 seconds.
Sets = 5
Reps = 12 (for each exercise)
