Here's a little secret -- twice a week I've been working out with people my mom's age and loving it. 

Maybe it's because I'm usually the youngest person in the pool, maybe it's because you can't get hot and sweaty in the pool, maybe it's because I get to wear all my new swimwear that I bought since I've lost more than 75 pounds. 

Or maybe because aqua aerobics classes are a damn good workout and it's super fun. 

Now that I have a Fitbit that I can safely wear in the pool, I noticed that each hourlong workout burns around 500 calories, which is not too shabby for feeling like you're playing with pool toys while Pitbull "dales!" in the background.

If you want to take the plunge (HA!) and try pool workouts, I have learned there are some things that are essential.

Don't workout barefoot

Aqua aerobics has a lot of jumping, shuffling, hopping and jogging, so it's important that there's a bit of a supportive layer under your feet. It'll just make things more comfortable and more enjoyable -- and it'll keep you from getting athlete's foot from the soggy locker room floor. There are some top-notch real-deal aqua workout shoes out there but I wanted to see if I could economize and get a happy medium between those and those drugstore cheap-o aqua socks. (Do they only sell stuff like that in Florida drugstores?) I found these slip-on water shoes and they seem to be holding up well -- unlike the water shoes of one woman in class whose shoes basically disintegrated in the pool last week. She was picking up chunks of rubber from the pool bottom at the end of the class. They drain really well, dry quickly and are relatively cute.

Wear a supportive swimsuit

There's a lot of jumping going on in the pool, something that on land would be considered really high impact. You need to hold those girls down so finding the right swimsuit is important. I have learned that floaty layered tops don't work (the layers just hang out in your armpit area) and flirty skirted suits don't stay where they're supposed to and you spend half the time yanking the skirted part down.

Tankinis are great as are sporty one-pieces. I got a cute purple paisley tankini at Swimsuits for All, but alas, I can't find it there anymore. I also got a sporty Reebok suit at Nordstrom Rack that's made for working out in. It's not there anymore either but here it is at Amazon.

Get a wet bag for that drippy swimsuit

Here's my tip for doing a "prewash" on your chlorine-saturated swimsuit -- take a shower at the gym in your swimsuit to wash off a majority of the pool water. Then instead of wrapping up your wet suit in your wet towel, creating a wet mess in your gym bag, get yourself a "wet bag" that'll tote your suit home and keep everything else dry. I got a set of two cute Alva Baby wet bags on Amazon, and what's great about them is that they have two compartments, because I found that one of my new swim tops bled a little on my board short bottoms. This way you can keep 'em separated.

Protect your hair

The first week, before I had my aqua goodies, my hair resembled shredded wheat, so I desperately googled how to protect your hair from chlorine because my mop isn't going to fit in a swim cap without looking ridiculous. The key here is to make sure your hair is already saturated with something good so your hair doesn't suck up the chlorinated water. Fresh water, hair conditioner, even coconut oil (greasy!) is supposed to work, but I found AquaGuard Pre-Swim Hair Defense, and it got enough good reviews that I decided to give it a try. First off, it smells fantastic and has a really nice texture. I put my hair in a ponytail, then squirt out a big handful of AquaGuard and coat the outside of my hair and all the ponytail area. It has made a huge difference in my hair's condition, and it also rinses out easily (unlike the coconut oil, I'm guessing).

Soak your suit

I bought a swimwear cleaner that's supposed to get the chlorine stink out, but so far it's not working as well as Woolite Delicate Care liquid and a splash of vinegar, so that's what I'm going to stick with. Just make sure to soak the suit for around 20 minutes, then rinse it well and hang it to dry without wringing it out, because that's bad for the fabric.

My gym has its own pool noodles and aqua dumbbells, so thankfully I didn't need to buy those or shlep them to the gym. But I did learn that even though the dumbbells are basically made from foam roller material it makes a difference what size you use. The bigger the dumbbell the more water resistance, so go big for a lot of "weight." But go thinner on the pool noodles because you want to be able to sink that noodle down under your foot to provide lower-body resistance, and unless you're King Kong, you're not going to be able to keep a full-size noodle under your foot.

(I learned that the hard and hilarious way on the first day!)

That's a pretty glass of water ... now, drink 10 of them.

Water is not my favorite drink. If I had my druthers (mmmm, druthers...) I'd swig Coca-Cola all day -- full sugar, full caffeine. But I don't. That's just crazy.

Aside from my morning massive mug of coffee, I drink water, and I have to force myself to get it down because, you see, I am a camel. I'm never thirsty. But my scale that measures everything shows that I'm in serious need of water.

So how do I get my water in? I glug it. No dainty sipping, no "put it in a pretty glass with a lemon wedge" trick. Instead, I swig it like a frat boy at a kegger.

I need a big ol' water bottle with a proper "guzzling nozzle." My fave is a 32-ounce Rubbermaid bottle with a flip top. In fact, Rubbermaid refers to it as the Chug Bottle (at right). Nice thing about it is that it's readily available, BPA-free and cheap, so you can keep a few of them around and filled. You just flip the top and chug away. It also fits nicely in most car cup holders.

So you've got the bottle and the water. Now I'll tell you what I put in the water. If I'm working out, I can easily drink it plain. But if I'm at my desk or watching TV I need a little something. Right now I have a packet of Emergen-C and a heaping spoonful of pink lemonade Metamucil in my bottle.

Metamucil serves a few purposes:

• Pysllium fiber is great for improving your cholesterol. The gelatinous fiber pulls the bad stuff out of your system.
• It's also good for adding a boost of fiber, which can help make you feel fuller.
• The slightly "gloopy" texture of the water makes it go down quicker, and isn't that what we're after? It literally gallops down your throat.

In the evening, my water of choice is another quart with a packet of Crystal Light Pure lemonade flavor (I'm all about the lemons). It provides just enough sweeteness to make the water interesting, and Crystal Light Pure is made with stevia and sugar so there aren't any artificial sweeteners or colors. Yeah, it has 30 calories per packet but it's totally worth it.

My goal is at least two of those Chug Bottles. If I get three, that's awesome (and 12 glasses, BTW). If that seems like a lot of water, you actually get used to it after awhile.

Do you have any tricks for cramming down the water?
