Does anyone have any suggestions on stretching techniques? Usually I just do max-ot style stretching.

Example:

Chest Stretching (Bench)
135 x 12
135 x 10
155 x 6
180 x 3
195 x 1

this would be for if I was going to bench 225 x 6 or something. Anyone for or against this? I always worried it would wear me out somewhat.
