Installing an inground lap pool at home can be a great way to invest in the future of both your health and your finances. You'll be able to work out at home instead of in the greasy air and teeny-bopper soundtrack noise of the health club, and you'll probably improve the long-term resaleability of your home - there are few things more attractive to prospective buyers than a pool suitable for both exercise and play.

The main question when it comes to lap pool designs is whether you have enough space to fit one in your backyard. The absolute minimum lap pool length is forty feet. A lap pool should also be at least eight feet wide and at least three and a half feet deep. Aside from this, everything's rosy - lap pools need much less water than your average recreational pool, and the linear, elegant look of lap pool design is much less likely to conflict with the style of your existing home.

Another option you might not have seen before is to buy an endless pool. Endless Pools. Inc. have been producing the best of these for years. They utilize a bunch of nozzles to create a current the strength of which you can adjust to simulate the effect of swimming fast, slow or moderately, all without moving an inch. People call it the treadmill for swimmers, though it's actually a lot better at simulating the exercise of swimming than treadmills are of simulating running exercise - in fact, studies have shown great improvement in form by athletes who use Endless pools to help them improve their hydrodynamic motion through the water. The company now even produces a movable unit called 'The Fastlane' which can be installed in any pool, for an effect that really gives you the best of both worlds. For those who are most concerned about space, there's no reason your hot tub can't double as an endless pool - it only needs to be about half-again the length of your body.

What's great about endless pools is their low level of electricity consumption, so low they'll barely make for a blip on your water bill. The reason is that they're hydraulically powered for maximal efficiency. Of course, nothing beats having a pool built according to full length lap pool design to train in, but an endless pool is both a showpiece and a great way to get your family back into the water and on track to a healthier lifestyle.
