SELEWARE Glute Ham Glider Heavy Duty Ab Glute Glider Machine, Exercise Wheels for Smooth Hamstring Curl Abdominal and Leg Workouts, Multifunctional Ab Glute Machine for Home & Commercial Gym

Mostly I work hamstrings via RDLs, but I recently got a hamstring roller as a cheaper option than getting a nordic bench or machine. Doing hamstring curls with the roller absolutely smokes my hamstrings. I got this off Amazon for $60, the build quality is really high - serious metal, excellent wheels. https://www.amazon.com/dp/B0DHRFRVTQ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1
