Its not always that straightforward.
Someone with longer femurs WILL lean forward considerably more than someone with normal length or shorter femurs (relative to HIS lower leg obviously).
Of course, the OP could just be having trouble getting his glutes/hams to fire at the bottom. Glute activation exercises would help here.
He could also have a weak midsection…in which case he needs to train his abs heavy. Kneeling cable crunches and weighted hanging leg raises (or on the forearm support pads) going heavy will help imo.
OR he could just have long femurs, in which case he is gimped as far as heavy squat poundages are concerned. Do your heaviest sets with a belt and also train your lower back and posterior chain with good mornings and these will allow you to go heavier in the squat.
Hip belt squats are also a viable alternative.
and finally, Zane leg presses (with the feet in the calf raise position) and done with NO bounce whatsoever but with full ROM may be a good replacement for the full ROM QUAD loading at the knee joint you get with ATG squats but MAY be bad for your knees. I’d check with “bushidobadboy” on this one if you want to try this.
a common mistake when doing back squats (particularly when going low) is having your back bend way down with the butt going way out as you go low. I have seen people doing low back squats who’s back go parallel to floor as they go down. You should look in the mirror when your doing squats to see if your back remains perpendicular to the floor ; if its going parallel-- you have turned the squat into a lower back exercise (which its not meant to be); check your form.
anybody have a video showing the improper squat (where back goes paralell) vs a proper squat where back remains upright; might help op.[/quote]
