Best Abs Wheel
Fitnessery Ab Roller

Upgrade your planks with this abs wheel, which comes with a few extra perks, including a knee pad for added support, and an abs workout e-book in case you're stuck on what specific exercises to add to your fitness regimen. 

Not only will this ab roller strengthen your deep core muscles and obliques, but you'll also work your glutes and shoulders, too, says McCowen. 

How to: Start in a kneeling plank gripping the handles, engage your abs, and then slowly push your hands out past your shoulders, gradually increasing how far you go as you get stronger. The key is to keep your core tight the entire time. 

Rave review: "Great ab roller. The price is awesome considering that sometimes equipment like this can be overpriced. It came with a knee pad which I wasn't expecting which was a nice surprise because that can be the downside of using equipment like this if you don't have a mat at home to use. The wheel itself it well made and sturdy. I've used ones before where I'm worried that the handles are going to snap off and this isn't like that at all. It's incredibly durable." —Dorothy Z., amazon.com
