I have tried this a several times with a few session ladies. Off the top of my head the two that I remember are Renee Toney, and Colette Guimond, I actually have a video of Colette bench pressing me and doing push-ups with me on her back. I also saw Becca Swanson in New York City and she also did push-ups with me on her back and many other lifts. I’m going to see Ripped Princess soon and I definitely will test this out on her. Lol.
