I don’t know what it is about ab trainers, but I seem to be especially intrigued with any new system that is released to the market. I have tested a lot of these units, and I can tell you that 80% of ab trainers on the market do not work as advertised. But those that do work make life easier for you and make it easy to get a work out in even in the smallest spaces. I have discussed a few top abdominal trainers in a previous post but here are 3 more compact ab trainers that you can use in your apartment even if it is too small:

Total Core Extra: it is selling like hot cakes. If you have watched TV on a weekend or late at night, you may have seen the commercials for this innovative product. It’s designed for beginners who want to work on their abs in the comfort of their homes without putting too much pressure on themselves early on. If you are a bit advanced, you can pass on this.

Back Stretcher & Ab Trainer:  Whether you have backaches or just want to improve your abs, this somewhat compact machine comes in very handy. It’s an affordable system that reduces back pressure, improve flexibility and alleviate pain. But it works as an ab trainer as well.

Power Wheel: we have all seen those basic exercise wheels. This is an exercise wheel on steroids. It lets you work on your upper body as well as your back. Helps you increase your flexibility and challenge your core muscles. You can perform push-ups, pike-ups, inch worms, and leg curls. Best of all, it’s so compact, you can use it anywhere.

What’s your favorite ab exercise machine?
