i am a 207 pound (94 kg), 5 foot 11 inches tall, 17 year old male. i sprint 50 yards, jog back to the starting position, then do extremely vigorous shadow boxing for one minute, all without rest. i then rest for 30 seconds then repeat. I do this for 12 rounds. i do this every other day. with this regime, can i quickly increase my metabolism and most importantly lose a significant amount of body fat? And also how long until i see results? Thanks
