Ben, anecdotally before the evidence police jump down your throat:
Im assuming the junior sprinters havent done that much lifting but have any other guys in your group or anyone else you know implemented this lift? If so, any decent improvement on the track? do they feel similarly more powerful?
Have you heard of anyone picking up any injury that they could trace back to introducing this lift?
Have cleans, deads, squats felt easier since you’ve been pushing the weight up on the hip thrusts?
Have you felt more powerful in any aspect of hurdling: into h1, off the hurdle, between the barriers?
Do your jeans still fit?
