Interesting EMG data - UK-Muscle Body Building Community

EMG or Electromyography, is the study of electrical signals produced by muscles. This study shows which exercises activate certain muscles the greatest. Very useful if you want to develop a certain muscle to the exclusion of others. The greater the EMG signal, the greater the activation of that muscle by that exercise.

Excellent post SD

Does anone know about dips? You can change the position you do them in(leaning forward, straight up or leaning back) by using your legs to offset your weight. does one way put more strain on the chest than another or is it all pretty much the same?

Is the Gastroc the inner calf muscle?

Gastrocnemius is the big calf muscle that sits at the rear of the lower leg. It attaches via the achilles tendon to the heel and provides plantar flexion of the foot and flexion of the knee.
