| I position the seat so my knees touch my chest and go. Granted I worked my legs all session but I couldnt get halfway at 400lbs. But if i moved the seat back one notch I coukd max out the machine at 480 fairly easy. Id venture to say more leverage but a little less movement. Which is the correct way? For reference two notches back was easier yet but again less range of motion. |
| The majority of people are going to have their low back rounded over to touch their knees to the chest. While your back is supported by the seat it doesn't change the fact that a rounded lower back in the leg press is going to assymetrically put forces on your vertebral discs that can lead to a bulging or ruptured disc. So uses a range of motion that allows you to maintain a safe spinal position. |

Flexing spines are weak, vulnerable, etc. as Kasab said. For Leg Press, You should arch your back as hard as you can, just as with squats, and not lose the arch through the whole rep. knees can come up to your chest, but keep good form with your lower back. I'm not a huge advocate for leg-press aside from a high rep accessory exercise, as it can isolate the quads fairly easily and help build tendon strength. I prefer other exercises for quad and hamstring isolated work. For Future reference: "Maxing" on a Legpress is like stapling your nutsack: You might think you're hardcore because of it, but really you're just 'tarded.  |

I use the term "max" because that's the maximum weight on the machine. I don't know what other term to use? I was not bending forward, I was using the seat back and tightened my core. I just positioned it so close my knees were almost touching my chest. Giving myself a couple extra inches made it so much easier. And for reference I'm staying away from squats and deads until the doc says otherwise. You can argue all day long what do they know but I like to play it safe. I just wanted a little leg work with all the back work I was doing. |
