Way too busy? Try HIIT!
Are you crunched on time and still want to burn fat and build lean muscle?
Try HIIT which stands for High-Intensity Interval Training. HIIT can be performed during cardio or weight lifting. Cardio HIIT is done by going "all out" for X amount of seconds (10-30s) and then walking at a moderate pace for 1-2 minutes. This method is to be repeated for the duration of your cardio session. (Be sure to stretch first)
HIIT performed during weight training is similar to cardio HIIT. The difference is in the recovery time and how the exercise is performed. Instead of taking a 1-2 minute rest between sets, it will be 10 seconds. The workout will be performed in a circuit format with 3-4 exercise.
