Why you should train your hip flexors with Glute-Ham Developer (GHD) sit-ups 🔥 ➡️ post-modern athletes are hip flexion weak and it affects most performance ➡️ weak hip flexors assure weak abs - especially weak lower abs. No amount of crunches can compensate ➡️ Without static contraction or stabilization exercises, the abs never learn to perform their most critical but most functional role - the midline stabilization. The Suprfit GHD‘s Ariald and Berengar are now available in allblack and ready to ship 🖤 #iamsuprfit #suprfit #fitnessequipment #glutehamsitups #glutehamdeveloper #ghdsitups #hipflexors 📸: maximilian.kelm idyllove crossfit_go_ahead
