For powerlifting:
1) Board presses, yeah I'm dumb I just have no clue what they are or how you do them. Any help?
2) High bar squats, again I have no clue what they are, any help?
3) Dimmel deadlifts, again I have no clue what they are, any help?
4) Manta Ray squats, again I have no clue what they are, any help?
5) Box squats, I've read different things, but box squats are just squats where you go down (below parallel), sit on a box, then go up. Is this right?
Big BIG Thanks for any help!
