Because of my essential tremors I couldn’t ever bench very much, but I could leg press 1000 pounds. That much weight hurt my spine though, so I usually would do 500-700 pounds 10-15 times. I didn’t need to train or practice for it, I just tried one day and my legs are naturally that strong.
My schools gym needs some 100 lb plates...the leg press machine only holds 10 45s (450)lbs....I am good on that for 4 sets 15 reps. I would be interested to see what I could leg press.....I am with you on those big oak legs....good for power and sprints.....wasted on distance running though.....did I mention I hated running even when I was 190lbs.
