Chains = Variable Resistance
When you lift with chains, the weight gets heavier at the top of the movement. Each time a chain link leaves the ground, you’re lifting the weight of that chain link, so you’re lifting a little more.
Well, as you lift each of the chain links off the ground, the weight of the chains is released from the floor and increases your load. The increasing load of the chains makes it so you have to maintain the greater force (or at least a portion of the force) you produced during the initial lift. You have to keep exerting force to counteract the increasing load. **NOTE: Usually, you exert the most force at the bottom of the movement.
When you bench press with chains, the load increases as you press up since the chain links are leaving the floor.
You have to keep exerting force throughout the top of the movement, as the chain links leave the floor.
The load decreases as you lower the bar since the chain links are going back to the floor. You exert less force as you approach the bottom of the movement. The load increases during the concentric movement and decreases during the negative movement.
When working with **CHAINS**: The weight gets heavier as you lift it. You have to work harder to keep lifting it. The load is the heaviest at the top of the lift. The weight gets lighter as you bring it toward the ground. The load is the lightest at the bottom of the lift.
