Could you tell me what a Peterson Set-Up is? Is it a sit-up variation? Also, I've heard of Scott Curls (Preacher) but what is Scott Presses? Is it similar to Arnold Presses? Thanks for your time and knowledge!

Peterson set-up is a set-up single leg on a box using weight driving off the leg you are using. One arm scott press is db overhead tricep ext single arm.
