A properly performed crunch is one of the most well-known exercises and is a great way to strengthen your core (the foundation to all movement). Properly performed being the key phrase, because many folks tend to do them incorrectly. Often, people strain their necks and backs with incorrect form or have difficulty getting down to the floor to exercise in the first place. Enter: Fitnation Core Lounge Ultra workout chair. This handy chair is over $90 off right now on QVC.

The Fitnation Core Lounge Ultra is designed to stimulate crunches in a full-body supported chair. With traditional crunches you are only able to lift up—and contract your core—as far as the flat, hard ground will allow, but with the chair, you can extend past 180 degrees.

Here's how it works: The stable, steel frame holds a mesh chair that cradles your head, neck and back, then hand holds and adjustable foot pedals help you maintain proper form while you do crunches. The crunch movement strengthens those oh-so-important core muscles, which protect your spine and keep your body steady and balanced.

The Fitnation Core Lounge Ultra workout chair with rep counter and 30-day FitPass is typically $262 (if purchased separately), but it's on sale right now at QVC for just $169. The accompanying 30-day Echelon FitPass gives you access to yoga, strength, kickboxing, core, toning and HIIT workouts you can complete from your living room. And for those stat-obsessed junkies, the rep counter can help you track your progress. The chair holds up to 250 pounds and folds up for easy storage. The chair is available in blue, black or purple (a QVC-exclusive).

Feeling skeptical? So was this user, but now she says: "Wow this works, I've been using everyday...I can feel I'm toning my stomach muscles." Another happy customer said it's a great tool to add to any workout schedule—"I love adding different equipment for my workout routine and this is a very nice change to add when either I want to use my Total Gym, my Bowflex TreadClimber TC5000 or going out for a nice bike ride."

With the importance of a strong core for all kinds of movement—from running to dancing, golf to tennis—the Fitnation Core Lounge Ultra workout chair with rep counter and 30-day FitPass is the gadget to get your fitness routine off the ground.
