Horizontal force production

[Brookfine]

Miami has been brutally hot this year, so it's looking like I'm going to be focusing on strength training until October instead of sprinting.

In the past 3 months I moved from (365, 275, 405) to (435, 325, 515) on SBD while maintaining speed on one track workout a week. With the next few months I'm wondering if I should be adding a lift that might work horizontal force production more, but I'm not sure what that would be.

I'm curious if sleds might be a good idea but I've seen some horrifying ankle injuries watching videos of strongmen pushing sleds and pulling cars. Is there a barbell lift that trains that horizontal force production to the same degree?

How is horizontal force produced differently such that it needs to be trained specifically?
