Designed as an exercise roller and ab roller, it supports core-focused, abdominal, and full-body bodyweight training movements on a flat surface. The four-wheel roller design helps the single-roller smoothly across the floor, making controlled forward, backward, and stability-focused exercise patterns easier to perform. As a core-focused training roller, it adds a practical difficulty to workouts by engaging the midsection while supporting balance, coordination, and repeated motion exercises. The single variant includes two coiled resistance bands, giving the fitness equipment an added training option for users who want more exercise variety.","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/4e384b90-3022-42ae-88c7-acabd289c00d.jpg?v=1786241438","href":"/product/wp-dcd-10001253281.html","buy_url":"https://uecyem-u1.myshopify.com/products/wp-dcd-10001253281","buy_url_source":"shops.shop_domain + product.handle","seller_name":"uecyem-u1.myshopify.com","seller_url":"https://uecyem-u1.myshopify.com/","return_policy_url":"https://uecyem-u1.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/4e384b90-3022-42ae-88c7-acabd289c00d.jpg?v=1786241438","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":0},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/557ed96c-5c35-4c35-9d86-5b82b5f0c363.jpg?v=1786241403","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":1},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/fd0e3333-4877-4f7c-b794-21c799f3d1d8.jpg?v=1786241425","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":2},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/14c740d9-16df-494b-8645-0aacb2457c76.jpg?v=1786241435","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":3},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/f0b25b56-c225-4541-b763-14578ec81d79.jpg?v=1786241409","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":4},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/20e0de70-5302-4dd0-bd58-c31436e60206.jpg?v=1786241435","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":5},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/51d755ed-6c84-4523-b31b-b83dda77b7b1.jpg?v=1786241428","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":6},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/e1db9398-4a89-450d-a394-a743e3061e3f.jpg?v=1786241411","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":7},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/da11cf67-9c0d-4e67-9a34-358879cf7743.jpg?v=1786241415","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":8},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/8ae8d16b-592e-490f-b715-2e87a816d029.jpg?v=1786241434","alt":"Four-Wheel Roller Metal Frame Core-Focused Training Roller Stomach Workout Wheel Caster Wheels Long-Lasting","position":9}],"related":[{"handle":"wp-dcd-10001426086","title":"Hanging Ankle Cuffs with Assist Rope | Heavy Duty, Padded, Inversion Cuffs with Metal Hooks, for Pull up Workouts","category":"Fitness Equipment","price":"$54.07","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/658edf44-343a-4958-9dd1-2bed7895e26f_cdfc9dae-8b38-435a-9836-98fc05056c4e.jpg?v=1787671995","sku":"dcd-30004042978","href":"/product/wp-dcd-10001426086.html"},{"handle":"wp-dcd-10001421284","title":"2 Pieces Non-Slip Slant Squat Board | space-saving-Saving Design, , for Strength Training","category":"Fitness Equipment","price":"$34.16","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/dcc0dc2d-0ae6-4810-9add-3369661df39d.jpg?v=1787672107","sku":"dcd-30004030894","href":"/product/wp-dcd-10001421284.html"},{"handle":"wp-dcd-10001417813","title":"Non-Slip Curved Arm Exerciser | Three Central Grip Positions Metal Frame, for Home Gym","category":"Fitness Equipment","price":"$28.10","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/33b7af74-d3ee-4831-9a15-5484dec6e26d_1a352d68-d497-4b45-aa23-df4abbbe479e.jpg?v=1787672093","sku":"dcd-30004022751","href":"/product/wp-dcd-10001417813.html"},{"handle":"wp-dcd-10001413571","title":"Muscle Recovery Leg Fascia Circlet | Post-Workout, surrounding Leg, for Home","category":"Fitness Equipment","price":"$13.86","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/68d1f3b3-f1d1-4327-9008-52a5ea477901_7d047cc7-49d7-4d34-8a9a-db49136351ce.jpg?v=1787670825","sku":"dcd-30004010994","href":"/product/wp-dcd-10001413571.html"}]}}
