Some machines, like the Core Max Smart Abs Machine, fold up for easy storage, while others, like the Ab Coaster PS500, are bulkier and require more space.

If you want to work more than just your abs, consider machines that engage multiple muscle groups, like the Fitlaya Fitness Core & Ab Machine.
5. Budget
Prices range from under $50 to several hundred dollars. Set a budget and choose the best machine within your price range.
