have you ever come across a client (or have you experienced it yourself) that can’t really feel his/her hamstrings working properly in posterior chain exercises?
A good friend of mine has some serious issues with this. On the RDL’s he’s engaging the core/glutes, keeping the bar close to his body & focusing on pushing the hips back and forward. Even though his form is good, the most he gets out of his glutes and hams is a little stimulation but not that burning sensation.
His lower back tends to take over pretty quick once the load gets heavier even though form is good. I’ve even made him use a band around his knees during RDL’s to further increase the stretch on the hamstrings, but his lower back still gets aggravated after a couple of sets. I believe he is extremely lower back dominant as he tends to feel this body part also taking over in movements like the deadlift and leg press. Sidenote: he’s more quad dominant, has weaks abs and has posterior pelvic tilt only when sitting. Whenever his standing his pelvis is neutral.
His hip flexors and upper hamstrings are a bit tight but not extremely tight. He can go down to 90° on RDL’s without the lower back rounding.
On isolation movements like the lying leg curl he also can’t really stimulate his hamstrings and says the hip flexors and adductors are mostly taking over the movement. A hamstring pump is non existent for him. I’ve asked John Meadows for advice and his answer was to completely relax the feet, toes out just a tad, slow eccentric and hard contraction. This also didn’t work for him.
I’m pretty sure he’s a type 2B because he’s always trying to please everybody, thinks with his emotions, loves food and has mood swings every now and then. Feeling the muscles that he’s working on is extremely important for him. If he can’t feel it, he gets really discouraged.
I’m starting to think his issue could be neurological? Like for example due to improper neurotransmitter efficiency of acetylcholine and adrenergic desensitization? If i’m correct, these neurotransmitters are mainly responsible for hard conctractions (next to proper mineral function of course). His diet and supplementation regimen is on point.
Does anyone have advice to target his issue? Any help would be greatly appreciated!
