I’ve seen it recommended by a few coaches, because, if you take a long step and keep tibia vertical and trunk upright you’re meant to strengthen the glutes at the same time as stretching the hip flexors.
That’s the theory at least - trouble is - I do them long stride vertical tibia and trunk, yet I’m sure they’re doing the opposite - strengthening my hip flexors and stretching my glutes. Often the back leg is fatigued before the front leg - the back leg is the limiting factor. That isn’t right at all… Is it good for anterior pelvic tilt for the hip flexors to be stretched (and fatigued) under load?
I don’t know what I’m doing wrong - I stretch my hip flexors throughout the day constantly whether training day or not - I spend a LOT of time each day stretching each hip flexor. I also do a hip flexor stretch/glute bridge complex before doing RFESS to hopefully quieten down the hip flexors and wake up the glutes - but it’s still the hip flexors of the back leg failing first.
Anything I can do to stop this problem?
