Overtraining, according to my teaching at moment. Good thing to take a restie. Bad for you really.Know what it is like, did it myself. Maybe add some strength training , squats and stuff for strong quads and hams - also will up your metabolism helping along with your cardio. You want to do some ST, if you want to lose kilos, cos you will burn hard earned muscle too, unless your helping it to be put on. This will cause your metabolism to slow, making it hard to lose weight.
