Start by adjusting suspension straps to a secure height and stand facing away from the anchor holding the handles. Step one foot forward into a forward lunge while simultaneously performing a rear fly by extending your arms out to the sides and slightly back. Focus on keeping your chest up, core engaged, and shoulder blades squeezed as you push back to the starting position. Alternate legs and repeat with controlled movement.
Log your suspender forward lunge with rear fly sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
