There comes a point when dips just won't get you the gains they used to. Once that happens, adding more and more reps won't build strength or muscle. But
manipulating the tempo will.
Slowing down the rep speed and adding 3-second pauses at certain points throughout the ROM (range of motion) will help you own the movement. This method works with regular parallel bar dips or ring dips.
Scot Abel is a bodybuilding anarchist. He doesn't believe in tempo training, pre-determined rest intervals, back-off weeks, or the fact we have elves in the basement that make Metabolic Drive. What he does believe in is pretty cool, though.
