OMEGA does great work. He made a sport specific program for me and results have been outstanding, much better than I expected.
His diet is unlike the tradional bodybuilding diet, but is more effective IMO. I can't go into detail really.
Know this though, FORM IS EVERYTHING. The way he has you work, you won't push as much weight, so ego goes out the door. The muscle do ALL the work, so several things hapen:
1) Muscle get more stress, resulting in more growth.
2) Ligaments have less strain on them, reducing the risk of enegry, both to them and the joints themselves.
3) Form and mind muscle connection are very important, so you learn to FEEL every muscle group work much better. This makes sure you really work the desired muscle group well.
4) Through his lifting system, order, warm ups, ect (listed in his program) you maximize your time in the gym. No time or lifts are wasted. All have specific reasoning, both through his personal experience and through his studies.
No reason to doubt him. Hes worked with a lot of people, and I have never heard a negative thing from his training. I've lost fat, lost total weight, while adding a good deal of strength in EVERY lift I do. Well worth the money.
