OBS-BA30 Abdominal Crunch & Back Extension Machine

Thigh support pad

It’s a handle-free leg stabilizer, made with padded, height-adjustable construction. It fits snugly around users’ thighs (suiting various body sizes) to keep legs steady during crunches — letting you focus fully on activating your abdominal muscles without relying on extra leverage.

Lumbar support pad

It’s a padded, contoured roller that fits the lower back. When doing back extensions, it supports the lumbar area to keep the spine aligned, letting you safely and effectively target your lower back muscles.

Pin-loaded weight stack system

It’s the resistance control part for both crunch and back extension exercises. The yellow pin lets you easily adjust the weight level (by inserting it into different slots), so you can tailor the workout intensity to your fitness level. The perforated panel around it helps keep the system cool during use.
