Doing Negatives for Strength and your 1RM

[big_bad_buff]

Ive heard these can be used in a power/strength training program to increase your 1RM.
Anybody know what place these have in a power training program?

i know it puts a tremendous amount of stress on the old pecs. just another variation i would think. try using chains if your wanting to better your bench press, i promise this will help your 1RM
