I've recently added Sled Work to my routine 2Xs per week. I am on week 3 and already increased my squats. I have to say that I have never gotten pump like this in my quads.
For the most part i start with a few plates and walk until i burn. then add more. when i exhaust moving forward I squat and pull ass to grass. adding more plates throughout the workout.
Each routine is 1hr long. I've found Sled Work to be a hidden gem in Bodybuilding. If you are looking for something new I highly suggest it. I used my 1 hr I was swimming laps in a pool and now I walk laps with about 315lbs on a sled,
I don't get as detailed as the BB.com shows on this link https://www.bodybuilding.com/fun/push-pull-perspire-7-sled-workouts-to-leave-you-in-a-heap.html but it's useful if you have no idea what I'm talking about.
