Anchor a resistance band overhead (e.g., on a pull-up bar or door anchor). Stand facing the anchor and hold the band with both hands, elbows bent and tucked close to your sides. Extend your elbows by pushing the band downward until your arms are fully straight. Squeeze your triceps at the bottom. Slowly return to the starting position by bending your elbows, maintaining control and tension in the band.
Log your band pushdown sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
