Decline Bench press

The next lift is the decline bench press.

This lift is as it is named, the bench press but down a declined slope.

The decline bench we were using was at a 45 degree angle downwards.  This 45 degree angle changes the way the forces affect the lifter, instead of the forces being balanced upwards and downwards, there is also a friction keeping the person in place.  This degree really doesn't affect the actual pressing motion.  The actual pressing motion is a straight up and down motion opposing the force of gravity, but is greater





.  The sum of the forces is equal to the work being done by the press, therefore, the equation to find the work and power is the same.  The work equals 374.678J and the total power generated in the lift is 1023.710 Watts
