Already 2 months that I'm training in HIT fashion, and I can't complain... I'm workin out 3 times a week and spending about 15min each workout session in the gym. So far everything's fine, I've managed to add reps, sometimes weight to each exercise each week. There were a couple exceptions were I stagnated but usually the next week I can add some repetitions to it. I've tried a couple of training plans before during 3 years (I started with 17). I started with a full body routine 3 times a week, then I split the training into upper body and lower body and alternated between these two workouts every other day. Then I trained 4 split, 4 times a week, after that I tried to train three days in a row and then take one day off and again train three days in a row. So far HIT was the best training experience I had. I feel really good after each training session and this sort of training gives me ample rest, so I'm not stressed out the next workout... the times where I trained 6 days a week for about an hour sometimes two were insane... I had no power, was tired all day etc. For me HIT is the most scientific training out there and is based on reason instead of human intuition. It's really all about giving the body a strong growth signal in the shortest time possible, so that you don't destroy too much muscle tissue, when all you want is not endurance but hypertrophy.
I don't understand why many people accuse HIT of being too dangerous and insecure for the joints and the muscles when in fact it's one of the most secure training forms that exist.... 4 sec + 2 sec hold 4 sec - the muscle is doing all the work, no momentum involved, so the joints don't get much stress.
I'm no professional and I certainly do not look like one, cause I was always clean, meaning not even drinking whey protein and shakes and still being one of the stronger guys among my peers with 6'4" and 240lbs... it seems that i'm gonna continue to train HIT way for a long time..
