In a study done by Pharmatech among three groups of male subjects engaged in a weight training program, the two groups that used Belizean Man Vine extract gained lb and lb, respectively, more muscle mass than the placebo group over an eight-week period. The benefits reported, which were universal to all test subjects, are increased muscle mass, improved recovery times and increased strength. What is of particular interest is that group that gained more lb of muscle did so on a diet that consisted of 50% of the calories and protein than that of the group that gained lb, clearly demonstrating the anti-proteolytic action of the extract. It is also likely that the phenylethanoid glycosides can both increase recovery and enhance nitric oxide production (from histamine inhibition) may be contributory factors to the acquired muscle gains.
If you are looking to put size on try a program called P90X. The program is very intense and even caters towards athletics. Cuation, this program is extreme but works wonders…I started at 175 lbs and 22% body fat at 5’″ at 26yrs old and know down to 17% body fat after only 3 months. They even suggest what foods to eat and how much depending on what you want to do. The programs are brole down into toning, weight lose, and building muscle mass. The program is a little high priced but real worth it. I take creatine with my workout and seemed to do wonders. As far as speciallized workout for football, I have a very close friend who has been a varsity coach for 10+ years and said he has never seen anything like this program…….he started making his players do it in the off season and plans to set something up for summer workouts…..trust me, this program will give you great results!!!
