Is this picture true ?

No theres still the same force on the spine. The force exerted by the legs outwards puts an equal force back on the spine/fulcrum theyre attached to. Theres no way around it. If you have scoliosis, leg press might be better, but theres equal chance to injure yourself on both ways.

Also, address the previous post when this was posted on the other thread you just downloaded it from you autist. Shearing forces are significantly worse than compressive forces. Youre gonna experience shearing forces either way if you have scoliosis.

are you dumb?
the only force on the spine during leg press is that due to hamstring tension.
there is no compressive force.

I never said there was. This was part 2 if my original post when this autist posted this 30 seconds ago. There are shearing forces on the leg press, which for a normal lifter makes it worse. The spine compresses vertically up and down. Forces perpendicular to this are considered shearing. The load in this case is placed orthogonal to the lifters spine, and if the lifter is pushing the weight by his legs, rudimentary laws of physics state that an equal force is placed back. Remember that the seat is sustaining the weight of your lift, meaning that weight is exerted back on your back. Due to the larger surface area, you can get away with more strain, but a misslip can injure you way easier than a normal squat for a normal person.

Again, scoliosis is different because the squat is no longer just a compressive force. It also begins to shear in that case. But generally speaking, you can load significantly more onto a joint compressively than by shearing.

Isn't spine compression and decompression good for you?
