The Magic is in the Machine™

Designed more for those serious about fitness, the E-Series range is equipped with the revolutionary Endless Pools® Swim Machine propulsion system. Providing a smoother, more consistent current that spans the width of the pool, this type of water flow delivers a realistic feel, mimicking an actual pool or fixed body of water. 

what is aqua fitness 560x350

What is aqua fitness?

Hot Spring's Endless Pools® range brings aqua fitness to your backyard. A hydraulic propulsion system generates a strong and steady current of water which you can swim, walk, jog or row against. The current can be precisely calibrated to deliver the exact water speed you need, meaning Endless Pools are perfect for everyone from Olympic athletes to the elderly.

Aqua fitness can take many different forms. It can be performed in static water, through aqua aerobics, core exercises and stretching. Other exercises require either a large pool, or in the case of an Endless Pool, a machine generated current to work against, by swimming, walking, jogging or rowing. Along with the ability to generate a current, the Endless Pools Fitness System range offers a number of optional extras including a built-in treadmill, a swim tether and a rowing/resistance kit, giving exercise options that are almost as endless as the pool.

Underwater Treadmill

Optional – yet essential –the Endless Pools Fitness Systems hydraulically powered underwater treadmill allows you to vary the speed from gentle walking to an invigorating run. For a more challenging workout, turn on the swim current for resistance against your core, leg and upper body muscle groups. The underwater treadmill’s low-impact running and walking options give you all the cardiovascular benefits without the bone-jarring effects often felt with land-based exercise.

Rowing Machine

Expand the performance of your Endless Pools Fitness System with optional rowing a resistance gear. The row bars attach easily to built-in anchors and/or handrails and provide a low-impact, full body workout. Rowing is so beneficial because it keeps your heart rate elevated and focuses on core strength. Attach resistance bands to the sturdy handrails to increase the degree of difficulty.

Is it good to swim every day?

All of the workout, none of the impact. Swimming does absolute wonders for your cardiovascular system and doing it every day helps to ensure that the benefits of aqua fitness are fully realised.

In Hot Spring’s Endless Pools swim spas you’re granted the opportunity to enjoy a daily swim without leaving home. Our compact units have footprints of 14m² or less, meaning that they can fit on decks and in even the most intimate of backyards. Temperature-controlled water is generated into a consistent current, making this the most enjoyable swim you’ll ever have!

how long swim cardio gains 560x350

How long should you swim for cardio gains?

Swimming in an Endless Pools swim spa is a low impact but high intensity workout. What ‘intense’ means to you will depend on your level of mobility and fitness. A great place to start is a daily swim of 10-15 minutes at a leisurely pace. As you begin to build stamina you can slowly increase the current while adding five or ten minutes every few weeks. Eventually you’ll be swimming for closer to an hour, and at a healthy pace!

With the ability to calibrate the current to the exact speed that suits you, an Endless Pools swim spa gives you ultimate control over your workout. Add in the convenience of being able to do this in your own back yard, away from the crowds and shared water of the gym or local swimming pool, and it becomes obvious why so many Kiwis are choosing to invest in an Endless Pool!

swimming vs running 560x350

Swimming vs running

To swim or to run? It’s a decision that many health-aware individuals have to make, and the answer will depend on your fitness goals. As far as burning calories goes, running has the slight upper hand: running at a good speed (10-12k per hour) will burn around 700 calories for the average person, while swimming at a good speed (50m/min) will burn around 550.

When you factor in the wear and tear of muscles and joints, swimming comes out on top. As a low impact exercise, swimming increases your stamina without sacrificing your body. Swimming is also better for building muscle.

Thanks to the Hot Spring Underwater Treadmill, you don’t have to make a choice between swimming and running. This optional feature folds out from the front of your Endless Pool, allowing you to enjoy all the benefits of running without the high-impact pitfalls.
