i like good ol squats,takes more to do a good heavy squat,involves more muscles,and is one of the most taxing on your body.lrg presses are also good for a change though................
I would never think about leaving Squats out of my leg day unless you are a gimp as GKing stated.
I can definitly feel the squats working more in my Ass and lower back.
I use the Leg Press to bump up the weight to find my max because I can't load it up a lot more than with the squat.
The leg press machine at my gym is a Killer Cybex Plate loaded machine that really leans back so you are almost lying with your legs straight over your head.
These are great for some but can be difficult for longer-legged people without the same leverage and biomechanical structure. Regardless, you should always be going at parallel at the very least.
Any movement that works against gravity is going to be tough and put a tremendous strain on the muscles being used, couple this with using massive muscles and massive weights and you have the king of exercises,
the best cardio is also skipping.
Im 6.1" dont know if thats enough to be a "longer-legged person" but I go all the way, dont think taller ppl have a bigger problem with it. As always dont use to much weight.
