Fair enough mate, depending on where there at. But saying he could get someone from 100-160 in a few month is a huge load of shit. Unless there eating 1000 calories over maintenance level which is just gonna get them fat, bodybuilders are after lean gains.
Lol. Are you serious. Plenty of people go from 100 to a 160 dead in a few months without getting fat. Don't kid yourself 160kg dead is well within beginner level and can hardly be used as an example of strength training not working for muscle growth.
