For a commercial floor it is the piece that covers lower-back rehab, glute work and hamstring work in one footprint.\r\n\r\n<strong>\u00a045-Degree Roman Chair or Seated Back Extension<\/strong>\r\n\r\nThe 45-degree Roman chair fixes the feet and lets the torso hinge over a hip pad. Pad height sets the emphasis: hips on the pad for the lower back, hips just above it for the glutes and hamstrings. The seated selectorized back extension loads the movement from a weight stack through a roller behind the shoulders, so the user sits upright and the load is adjustable by pin. The Roman chair wins on price and versatility; the seated machine wins where members need a set resistance and a fixed range of motion.\r\n\r\n<strong>What to Check Before Buying<\/strong>\r\n\r\nPad adjustment range decides who can use it: a chair that fits a 1.60 m user and a 1.95 m user without tools is a commercial spec. Look for a footplate angle that keeps the calves relaxed, a hip pad wide enough for larger users, and a frame rating above 150 kg of user weight. For a selectorized unit, a 100 kg stack covers most members.\r\n\r\n<strong>How to Use a Back Extension Machine<\/strong>\r\n\r\nSet the hip pad so the pelvis can tilt freely. Lower under control until the torso is roughly in line with the legs, then drive the hips into the pad to come up. Stop at neutral; hyperextending past the line of the body loads the lumbar spine for no extra benefit. Two to three sets of 10 to 15 reps, adding a plate across the chest once bodyweight is easy.","link":"https:\/\/tzfit.com\/ko\/product-category\/back-extension-machines\/","name":"Back Extension Machines","slug":"back-extension-machines","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/tzfit.com\/ko\/wp-json\/wp\/v2\/product_cat\/113","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tzfit.com\/ko\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/tzfit.com\/ko\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/tzfit.com\/ko\/wp-json\/wp\/v2\/product?product_cat=113"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
