A weight stack or a plate horn lets you progress the movement the same way you progress a leg press, which is what turns abdominal training from endurance work into strength work.\r\n\r\n<strong>H3 \u00b7 Types of Ab Machines<\/strong>\r\n\r\nThe seated crunch machine loads the upper abs against a chest pad or handles while the hips stay fixed. The ab coaster runs a kneeling pad up a curved rail, so the lower abs do the lifting and the hip flexors stay out of it. Oblique crunch machines rotate the torso against resistance, and ab benches add a decline angle to bodyweight work. In a commercial gym the seated crunch and the ab coaster are the two that stay busy.\r\n\r\n<strong>Plate-Loaded or Selectorized<\/strong>\r\n\r\nSelectorized ab machines change weight with a pin and suit high-traffic floors where members move through fast. Plate-loaded ab coasters and benches cost less and take standard plates you already own, which is usually the deciding factor for a home gym or a small studio. Both versions use the same movement; the difference is price, footprint and how quickly the next user can start.\r\n\r\n<strong>How to Use an Ab Machine<\/strong>\r\n\r\nStart light enough to control the lowering phase. Set the pad so the pivot lines up with the hips, exhale as you curl, and hold the contracted position for a count before returning. Three sets of 12 to 15 reps twice a week is enough for most members; add weight when the last rep stops being hard.","link":"https:\/\/tzfit.com\/ko\/product-category\/ab-coasters\/","name":"AB \ucf54\uc2a4\ud130","slug":"ab-coasters","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/tzfit.com\/ko\/wp-json\/wp\/v2\/product_cat\/64","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=64"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
