Sleds didn’t come around until Louis Simmons popularized then in early 00’s, then Prowler got big due to DeFranco / Dave Tate, now Rogue sleds are in. You also would have been jumping on wooden boxes, it’s all hard foam now. lol gym tech is totally different, why front. — PolitiTweet.org

@Cernovich I was doing those exercises as a teen in the 90's. 😒 And the plyometric box jumps are a fast path to patellar tendonitis.
