Sit-ups feel good using this attachment on the bench. I would definitely recommend this attachment.

Works really well for situps and if you flip it around it works great for nordic curls as well!

A Bells of Steel 6-12KG Adjustable Kettlebell, featuring a sleek black competition-style body and a silver handle, stands upright on the left. On the right, five black weight plates are stacked, highlighting the kettlebell’s customizable weight system. The scene is set against a clean white background.
