Seriously!
 

Switch your exercise programme

According to a Mayo Clinic study, your metabolism slows as you lose body mass. To stop your results from flatlining, swap your usual gym session for half an hour of kickboxing (to burn 431kcal) or don your wetsuit and get out on the water with a surfboard for an hour (635kcal).

I was thinking recently what new can I bring to my workouts however kickboxing was not first place, I mostly like super-sets and tri-sets.

How about you guys? What do you do to bring smth new to ur workouts?
