I have mentioned earlier the benefits you get from increasing HGH (Human Growth Hormone) production in your body. If you want to read some more about it, you can refer to my post about the fat burning hormones here. Here are the TOP 4 methods of increasing your HGH.
Max muscle usuage: Workout as many muscle groups at one time as possible. The more muscle you use, the more fatigue and exhaustion you will experience and therefore the body will release more HGH. Usually I recommend compound exercises but if you are not a beginner, then try to modify workouts. The idea is to activate your stabilizer muscles. But make sure you don't try to do a 250 lbs bench press, on a ball. You can seriously hurt yourself. Try doing all isolation movements like bicep curls, lat raises etc. on the ball. You can do some exercises on one leg as well. The main idea if engage more muscle than you usually would in a normal exercise. If you don't bench press too heavy, then bring your legs up in the air to work your lower abs. If you don't use heavy weights then try things like overhead squats. Ohh and do full body workouts in a weight training session. Not just once body part. Be creative and remember to be safe.
Low or no fats in your pre-workout meal: I remember reading that eating fats before a workout slows down the production of HGH. Some people recommend unsaturated fats before a workout for energy as they take longer to breakdown. That is for people who are not concentrating on HGH. There are some other reasons to workout as well you know :P
Don't take carbs till an hour after your workout: Some people might kill me for saying that and they might be right as well. The only reason is that one tends to take High GI carbs or simple carbs right after a workout which increase your insulin levels. Insulin in normal circumstances is an anti-HGH hormone. There are ways to increase both at the same time they are a bit of an extreme measure if you ask me. Not taking carbs after your workout can end up in low energy levels and slower and LESS muscle repair, so do this a couple of time a week to reap maximum benefits and keep a balance.
Get atleast 8 hours of sleep: HGH is released to its max when you go into deep sleep. After an hour after you go into deep sleep. If you don't get enough sleep, you can't get into deep sleep and therefore not get everything of the HGH.
I guess this sums it up...let me know what you think :).
