SETUP: Attach a resistance band under an incline bench. The great thing about bands is that we can rotate our grip if necessary. I like to be more diagonal on this one. Before you perform a rep, be sure to pin your shoulder blades back to maintain great posture.
REP: Brace your midsection by squeezing your glutes and driving your feet into the ground, then press one side of the band up, keeping it set to chest level. Upon returning that arm to the start position, press the other side the same way.
TIP: Ensure the non-working side is actually switched on the whole time by maintaining your posture. Keep your shoulders back & chest up!
