Ugh…who fills your end with that nonsense?
In your opinion the ONLY purpose for weight training is to gain strength. This is wrong.
You can use weights as general conditioning work. I fail to see why trying to lift weights fast will contribute to anyone running faster or jumping higher, because the action is still way too slow to impact speed. On the RFD curve, weights are on the slow end, if you wanted to do light/speed weights, why not do plyo instead?
My vid of a 150 p.clean it’s pretty much the same speed as 100, meaning when im lifting 88% its still a quick movement in relation to lighter weights. Oly squats are more explosive than half squats as well, and it’s lighter weight, full ROM, better for the knees, less back usage.
