Count Your Tempo

Count Your Tempo  Your muscle gain is in the eccentric movement and not as much in the concentric movement.  The concentric movement is away from the pull of gravity and moving the joints closer together (e.g., in a bicep curl the concentric movement is when the wrist moves towards the shoulder joint).  The eccentric movement is toward the pull of gravity and moving the joints further apart (e.g., in a bicep curl the eccentric movement is when the wrist moves from the shoulder joint back towards the floor).  Note, that delayed onset muscle soreness (the soreness you feel a day or two following exercise) is mostly associated with eccentric actions, especially during higher-intensity exercises (e.g., deadlifts).  You should never just let your eccentric movements fall, meaning you should never let gravity do the pulling without you controlling the movement.  Rather, eccentric contractions should control the rate of motion, slowing the downward movement against the pull of gravity.  There are numerous reasons for this, not the least of which is prevention of joint and muscular injury.  During your next workout, see if you can focus on your control of both the concentric and eccentric contractions by counting your tempo.  The commonly recommended movement speed of six seconds per repetition is broken out as 2-3 seconds for the concentric muscle action and 3-5 seconds for the eccentric muscle action.  How on track have you been between contractions?  What have you noticed in focusing on this?
