Remember the famous 8 Minute Abs? The classic mid-nineties VHS workout tape featured three spandex-wearing fitness pros on the grass, sculpting their six-packs in just eight minutes a day. Believe it or not, the concept was highly successful, to the tune of $20 million in less than two years.

While you’ll still need a healthy diet to reveal a ripped midsection and toned obliques, don’t dismiss what eight minutes of hard work done regularly can do for your core. If consistent, you’ll notice a tighter, stronger torso in just a few weeks, even if it’s hidden behind a few pounds.

The benefits of strengthening your abs extend well beyond just looking good. Having a robust core — even without a well-defined six-pack — will make you better at just about every activity. For example, a sturdy midsection can help you maintain proper running form, resulting in better running efficiency. You’ll also hold yoga poses longer and with more ease. A stronger core can even lead to better posture, preventing back pain.

The area in question consists of four main groups of muscles. The rectus abdominis is what most people think of when they say abs. These are the muscles responsible for the sexy six-pack. The other three muscle groups are the transverse abdominis (or TVA), external obliques and internal obliques. Ideally, you'll do exercises that hit all four.

Compared to other home-based fitness machines, core equipment tends to be much more affordable and easier to store. This makes owning more than one piece a viable option, which is great because it pays to switch things up. So, when 8 Minute Abs gets old, get that toned midsection you’ve always dreamed of with these marquee tools.

Ab coasters may look like a funny infomercial gimmick, but they sell because they work. Isolating your upper body forces you to engage your entire core to move your legs up and down a curved track. With a twist of the knee rest, you can target obliques. The best part? No more having to get down on the ground for ab work. Just kneel, grab the handles and crunch. Ab Coaster’s smooth bottom-up slider motion and natural arc make it easy to use and reduce stress on the back and neck, making it ideal for beginners and seniors.

No athletes have stronger cores than gymnasts. Their secret? Repeated bouts of hard isometric holds on bars and rings. Tap into that regimen with these extra-thick bars, which carry a 330-pound capacity and 14 inches of clearance to make it easier to pass your legs through. Word of warning: parallette bars are not for everyone. You’ll need a fair amount of upper body and core strength to get the most from a parallette workout. But if you want the abs of, say, Simone Biles, these are your ticket.

Step up your sit-ups, crunches and leg tucks with a Bosu Balance Trainer. Trusted most by commercial gyms for its durability and 300-pound capacity, this one is pricier than many similar products for a reason. Packaged with a downloadable guide, the soft, curved design not only makes exercises more comfortable than sitting on a hard floor but it also requires additional core tension to maintain stability. Just a heads-up: it’s completely normal for the ball to deflate every few days — no wonder it comes with a pump.
