Josh says: "This is a great exercise for core, legs, posture and upper body strength. We are often bent over on the bike, and having a strong core and legs to support that position is very useful. Also, the pulling action in this exercise is really useful on the bike when you have to pull up on the handlebars to get over obstacles, whatever the terrain might be. An overhand grip is performed during this exercise because that is the grip we have on the handlebars of the bike."
Beginner:
Bend forward at your waist with your knees slightly bent and your back flat, holding the
barbell with arms straight. Lift the barbell up to your chest using your back and scapula retraction, then back down (similar to a rowing motion). Maintain good spinal posture throughout, using your abdominals to stabilize and support the position.
Advanced: Try this exercise on a BOSU ball (flat side up) or on a stability ball.
