Easy Adjustment of Nordic Curl Straps: Our Nordic hamstring curls adopt heavy-duty mountaineering-grade adjustment buckles, which not only increase portability, but also improve the safety of use. Simply press the sturdy spring adjuster to easily adjust the length of the Nordic Hamstring Curl in 5 seconds. Our Nordic Hamstring Curl Bands are not only great for exercising to increase hamstring strength, they can also help you recover from hamstring tendon issues and improve sprints and overall stability. Multifunctional Workout Nordic Hamstring Curls: Our Nordic Curl Bands can be used for sit-ups, core training, razor curls, Spanish squats, core twists and more. Our sets do not come with mats. You'll want to train on your own soft pad, such as a foam mat, yoga mat, or pillow, to prevent knee pain. Beginners can use equipment such as resistance bands, spikes, Swiss balls, or AB rollers to help with their practice. If you feel unsupported, you should stop exercising immediately and rest appropriately. Compact Design Nordic Curl Belt: It takes only 3 steps to easily complete the Nordic curl setup and start practicing. Step 1: Adjustable hamstring curl straps adjust the length to your shoe size. Step 2: Slide the door anchor under the door and close the door. Step 3: Put your feet in and adjust the straps for a snug fit and start exercising. The compact design of the Nordic Curl Band allows you to take it with you wherever you go, so you can practice at home or in the gym.
