4-Wheel Upgrade Ab Roller Wheel

The Proxima 4-Wheel Upgrade Ab Roller takes the stability problem out of rollout training entirely. Instead of one or two wheels, this model uses a four-wheel configuration that creates a flat, car-like contact patch with the floor — it's physically incapable of tipping sideways. For anyone who's tried a standard ab roller and quit because they kept falling to one side, this design removes that frustration completely. The 4-wheel base also makes it the safest option for heavier users, since the load distributes across four contact points instead of one or two.
