Helped my son train for exams

Bought this for my middle schooler to practice for his PE exam. It's lightweight enough for him to set up himself and has really improved his form.

Compact and effective

I live in a small apartment and this stores easily under the bed. The foot fixator is comfortable and doesn't hurt my ankles like some cheaper models.

Decent but suction fades over time

It works well initially, but after about 15 minutes of intense workout, I have to re-press the suction cups. Good for short sets, not marathons.

Perfect for home workouts!

This sit-up assistant is exactly what I needed. The suction cups hold firmly on my bathroom tiles, and it makes doing crunches so much easier without needing a partner.

Great value but needs smooth floor

Works great on my kitchen linoleum. Tried it on the carpet first and it didn't stick, so make sure you have a smooth surface. Otherwise, very sturdy.

Solid build quality

The plastic feels thick and durable. I was worried it might crack under pressure, but it has held up well through daily use for a month now.

5 FAQ

Q: Is there a weight limit for users?

A: The device is tested to securely hold users up to 150 lbs. Heavier users may experience reduced suction stability during vigorous movement.

Q: Can children use this device safely?

A: Yes, it is suitable for teenagers and adults. For younger children, we recommend adult supervision to ensure proper setup and usage.

Q: How do I release the suction when I am done?

A: Simply lift the small tab on the edge of the suction cup to break the vacuum seal. Do not pull the device by the handle while it is still attached.

Q: Does this come with an exercise guide?

A: Yes, a basic printed instruction manual with diagrams for standard crunches and variations is included in the packaging.

Q: Will this work on a textured concrete garage floor?

A: No, the suction cups require a completely smooth, non-porous surface like tile, glass, or polished wood to create a proper seal.
