SETUP: Clasp two plates together in one hand. Do the same in the other hand. Stand up tall with your chest up & shoulders back.
REP: With your arms down by your sides, squeeze the plates together until you can’t keep your grip any longer.
TIP: I like to do this exercise in front of a bench. That way, you can take it to proper muscle failure then “escape” without fear of dropping a plate on your foot!
