I constantly feel the need to train. It's like an itch I can't scratch but I want to know whether I should push it. For starters, here is the schedule I try to stick to every week: MondayTuesdayWednesdayThursdayGym 0530-0645Gym 0630-0745Gym 0530-0645Gym 0530-0645Gym 1110-1300Boxing 1800-1910Run 1600-1730Gym 1130-1330Krav Maga 1900-2030Krav Maga 1900-2030 or TKD 1800-2000Gym 1900-2015FridaySaturdaySundayGym 0530-0645TKD 1000-1200Gym 1130-1300Olympic Weightlifting (College Activity) 1300-1345Gym 1230-1400Gym 1830-2000This is supplemented by a steady core workout every two days, and stretching every two days to improve flexibility and core strength. The rest of my spare time will be distributed towards studying for college (UK version of college not university), food and sleep. I am a 17 year old and I'm wondering if I'm doing too much? Every time I try to tell myself to chill I think of the stories of a Judoka who would train 12 hours a day - if he can do it, why can't I? Is this a reasonable program to stick to? I would be getting about 8 hours of sleep per day, good meals and cold showers to help with muscle relaxation and regeneration.
