First, 720 lb leg presses are nothing to write home about. Sorry, they're not. At your weight, even doing a 720 lb squat just makes you a merely decent drug-free powerlifter. (A 195-lb drug-free lifter who can squat 700+ is like a decent cat 3 bike racer - likely to crush any random person off the street, but in the right places you'll find literally hundreds of stronger people who can crush a 195-lb lifter who squats 700+. Just like at bike races there are a LOT of riders who can crush a decent cat 3. FWIW, I used to be a competitive powerlifter...)

Second, drop the emphasis on torque. There's a reason why NOBODY who cruises at 20+ mph does that.

Because mashing away at 50 RPM is not going to make you fast. High force means your muscles are burning carbs and not fat. You only have a limited supply of carbs to burn and when you're done, you're done. It's called "bonking".

And it doesn't even work for short distances/times. Track racers don't mash either.
