Hey every1 recetnly as of yesterday my tredmill broke. I have been doing HIIT for the last month. I'm in the cutting stage and for the first month I lost 8-9 pounds doing this. I have no problems with my weight training or diet, it seems as if all of this is working perfectly. I can run around the block if I want but I was wondering If i can use hitting the heavy bag as a subsittiue for 30 minutes 5-6 times a weak until the tredmill is fixed. Will this help with weight loss or will it slow it down? put me on a plateau? or what, any advice is nice
