I actually don’t do any hypers right now. Gonna work on hip flexion as pointed out earlierLitterally stop doing hyper extensions. You want your back to have less tone not more.
Do the opposite. Ab, oblique, hip flexor, split squat, left adductor. Tuck pelvis. Normal PRI shit.
If your hams are tight it's likely because they are in a lengthened position due to pelvis rotation. So you're habitually cranking them to take up the slack. You want to strengthen the opposite side to take up that slack.
Usually biking would put you in a nice flexed position. Maybe as you fatigue you start to extend, core fatigues, hip flexors fatigue? Could be all kinds of shit.
Reduce your distance and work back up.
See a good coach.
Maybe try shortening distance between handlobrase and seat, reduce top tube? Run a higher stem?
I ride about once a week sporadically so it’s probably due to distance and that I don’t ride enough. I also do want to raise my bars up some to get some additional height to them
