Kelly Baggett on gymnastics vs. weightlifting:
A lot of gymnasts can go directly into the weight room without ever touching a weight and throw up a double bodyweight bench press easily. Upper body progressions like chins and dips clearly offer impressive strength benefits to the athlete as well. However, most common sports like football, basketball, track, and volleyball are lower body dominant. Many team sport athletes perform lower body resistance training, yet I do not see most of these lower body dominant athletes utilizing their legs as efficiently as gymnasts use their arms. So, I asked myself, "what would happen if I used a series of progressions for the lower body similar to what gymnasts use for their upper body progressions?".....
I'm just saying that your useable strength will progress much quicker if, when possible, you get strong by mastering your bodyweight either before, or at the same time, you get strong with common weight training movements.

1. There are a multitude of smaller muscles that stabilize the hips, knees, and ankles. Think of the "rotator cuff muscles", but for the hips and legs instead of the shoulders. These muscle are hit hard by single leg resistance variations, yet so are the prime movers (the quads, glutes, and hams). Strengthening these muscles in conjunction with the prime movers seems to give the athlete an increased efficiency when it comes to gaining strength. When they do begin to focus more on loaded movements like squats, their strength quickly shoots up through the roof.
2. For the same reason that a chin-up not only builds strength quicker and builds more transferable strength than a lat pulldown, it enables them to develop useable strength that much faster.

I believe the single leg "knee to the floor" deadlift is the most under-rated strength training movement there is. It requires a great degree of glute strength, which is where it's at if you wanna be powerful. The pistol squat is like doing a bodyweight front squat on one leg and requires a great degree of quadricep and glute strength.
So, for Kelly Baggett(a very successful speed development coach), developing lower leg strength and power is better/faster if you first build strength with bodyweight movements.
The "single leg deadlift" he gives an example of is easier than Ido's shrimp. Some people call this a "king deadlift" and it's like the intermediate shrimp.
