Trying to get in shape? These Amazon fitness products should help

If you work out outdoors, you know it's hard to find privacy. Here's a brilliant way to provide yourself (and your crew) some "me time" for bathroom use, showers, changing, rain shelter and much more. It's made of water-resistant polyester taffeta and, as the name suggests, it instantly pops up and easily folds back into the included carrier.

More than 13,000 shoppers agree. "Purchased to have a place to go to the bathroom and change my clothes when camping in my cot tent. Works like a charm!" raved a reviewer. "I am 74 and can get my camp site put together in about 10 minutes all by myself. Of course you need to buy the five-gallon bucket and toilet seat also. But the whole toileting and clothes-changing issue was solved for under $50."

Smart fitness means lots of stretching and muscle love, before and after a workout. This roller brings it with three wave patterns, veering from thin to super wide ripples, depending on how deep your kneading need is. It's made of tough-but-firm foam, has five vibrating speed levels and, at just three pounds, is super easy to tote around in the portable bag. Yes, portable: It fully charges (via USB port) in less than five hours and will provide two hours of treatment.

Said one satisfied customer: "This little roller packs a punch. Well built, and charged ready to go when opened. I highly recommend this if you have back pain. I've tried massagers that just haven't done the trick but this roller has worked wonders."

Who says round-the-campfire sitting has to be uncomfortable? Look how plush-y these chairs are! The moon shape conforms to your back while also giving you plenty of space to lean. They set up and fold down in seconds and include a cup holder and reinforcements in the base to support up to 350 pounds.

"This is not your average grocery-store camping chair," wrote one Amazon customer. "This chair has a lot more padding and is so much more comfortable..... After sitting in my chair, my sister wants to replace all of her standard camp chairs."

What a futuristic take on working out! This cordless jump rope (yep, you read right) eliminates the risk of tripping and the need for the maddeningly difficult hand-body coordination that conventional jumping requires... all the while providing a vigorous cardio workout. The handles feature ball bearings inside and a memory foam exterior, keeping your motion smooth and your hands perfectly relaxed. And at just $15, they're a steal.

Chimed in one enthusiast: "I really like these! I’ve been using them for a few weeks and I don’t have any complaints. I think they’re made well and seem like this will last awhile if they’re taken care of. They’re lightweight but feel sturdy enough. The ball bearings allow for the 'ropes' to glide smoothly."

This is an Amazon bestseller for good reason: Resistance bands are an ultra simple, ridiculously affordable way to get stretched and toned. This set comes with five 2" × 12" bands of various "weights," a handy carrying case and an instruction guide.

"Got these a few weeks back and have been able to use them a bit for various workouts. Really like having them — so far they have held up pretty well," a satisfied customer wrote. "They come with a nice little pouch for storage, which makes it really easy for me to keep them in my gym bag and just pull out the resistance I need. Worth it."

"Basic" is right: If you're starting an exercise regimen, you're going to want a mat (or two, or three) for stretching, calisthenics, and to protect your floor from dumbbells or other heavy equipment. If you're contemplating a yoga practice, well, you simply can't do without one. This bestseller is super thick, easy to clean and comes with a handy strap for easy toting.

"I absolutely love this mat. It’s thick and comfortable...it’s durable and well cushioned yet firm. It’s perfect for workouts. Usually yoga mats aren’t thick enough to support your weight and they flatten easily. It could be so uncomfortable...this one is not like that. So happy with my purchase," said a reviewer.

Nothing's worse — and more dangerous — than finding yourself in the middle of nowhere with nothing to drink. Currently just $10 (down from $20), the LifeStraw turns just about any type of water drinkable. It contains a microfiltration membrane that removes 99.999999% of waterborne bacteria and 99.999 percent of waterborne parasites. The filter also removes the smallest microplastics found in the environment and reduces turbidity down to 0.2 microns.

"I am going to keep this one simple. Recently I got stranded in the backwoods of the Adirondack Mountains. I had run out of water earlier on the first day and used this until I was rescued on the morning of day three. THIS WORKS, this helped save my life. If you hike, YOU NEED THIS PRODUCT," said one Amazon shopper.

Ab rolls are an excellent, and brutal, workout, partly because it's hard to stay balanced during those extensions. At 3.2 inches wide, the Vinsguire Ab Roller wheel is broad enough to keep you centered and stable. Because it’s rubber, it won’t damage your floors. It also has soft rubber cotton handles, so you can focus more on engaging your core than maintaining your grip. Right now, an on-page coupon brings the price down to just $21.

"I bought this product to tone my upper half. It's very lightweight. Very easy to use. It was very simple to put together. All in all, I really like it," raved one buyer. "The knee pad is perfect. I put it right on the carpet for extra protection. You can feel it working immediately. I can't wait to see results."

If you're pressed for space and/or just embarking on a toning regimen, this item's for you. With wooden anti-slip handles for a good grip, these LifePro dumbbells offer six weight options, from 2.5 to 15 lbs. — just move the slider to your preferred resistance level and start lifting! If you're looking to build muscle but aren't going to be entering a Ms. Universe tournament anytime soon, this is an ideal choice. Also not heavy? Their $119 price tag.

"These are by far the coolest, easiest to use and [easiest to] store dumbbell set we have ever run across," a happy customer reported. "Our old set took up so much room, [with] each weight amount on different bars. This is not only a space saver but [makes it] easy to adjust between weights. The lever is easy to move and snaps right into place. The base holds whatever isn't in use with individual slots so they don't fall over. Very nice for at-home use and storage."
