It is not accurate at all. The machine is balancing the weight for you. That weight will NOT carry over to free weights.
MACHINES:
- Prevent the body from performing movements naturally. The human body did not evolve to interact with machines: the musculature of the body is designed to accommodate a range of motions that it can perform on its own. Depending on which machine you are using as a substitute, you may be working with a gimped range of motion, lifting at an incorrect angle, isolating one muscle group while ignoring another.
- Do not activate stabilizing muscle groups. In order to develop whole-body strength, you need to have strong stabilizers. Continue using only machines, and abandon any hopes of ever seeing true strength.
- Are easy. Strength isn't gained through dicking around and being a little *****. Somewhere down the line, you have to make it hurt, you have to embarrass yourself, you have to disappoint yourself. If you desire to move ahead, you will be leaving your weakness behind you in time, but first comes hard work.
FREE WEIGHTS:
- Demand full participation of major muscle groups and stabilizing muscles
- Offer any number of COMPOUND MOVEMENTS are the foundation of a strength training program.
- They're not easy. Working with free weights in a no-bullshit, tiring, difficult program will harden your body and mind to the stresses of training. As you continue to train you'll start to feel "good" during your workout. Later on you'll feel like a million bucks. Soon after that you'll probably feel like s*** because you didn't work out, so the next day you'll go out and get your iron fix and feel like a * beast, on top of the damn world.
