The 3 Shoulder Exercises Every Swimmer Needs (And Most Skip) | Marcel Smit

Shoulder pain is the most common injury in swimming — and for most swimmers, it keeps coming back because they’re not fixing the actual cause. In this video I’m breaking down the three exercises that target the root imbalance: weak external rotators and an underdeveloped serratus anterior that leave the shoulder unstable in the water. These are the exact exercises I use before every gym session. Since I started doing this consistently, I’ve had zero shoulder pain — and I’ve been swimming for decades.
