Some gyms have devices that are specifically designed for you to use when you watch television. Instead you should be Grunting, Sweating…look everybody knows when they are working out and what we’ve got now is a situation where we have been allowed to fool ourselves because it’s in the interest of the industry to maintain that charade.
Effective exercise is hard! And that’s all there is to it! It’s like anything else, if its easy, it’s probably not effective. The fitness industry is predicated on machine use because it’s only cost effective to train their staff on the use of those machines…in other words, it is cost prohibitive for any gym to hire a strength coach to teach every customer in the gym to do these barbell lifts, those of course being the most effective stimulus for results.
