Fjay- don't get me wrong cable curls (concentration,etc) have their place but I dont think trainees (esp new ones) use enough compound + heavy lifts. When I think back of how much volume I did in HS & college (thanks to the mags) I cringe. I see guys doing 25 sets for biceps (straigh bar curls, then dumbell curls, then cable etc.) they have very little size to begin with- Thats what I was referring to-
Its similar to diet, new trainees want the quick supplement fix (creatine, n02, hmb or the new micellar/casein/whey 120% more powerful protein.) while their diet is crap...or they just arent eating enough whole foods. Again most of these ideas are driven into our domes by the mags (every mag has its own supplement line or at least used to- i don't read em anymore)
sorry for the rant-...if cables work for you u then keep it up-
