\u201cIt was really an epiphany!\u201d Hoffman says, recalling that first swim. \u201cI feel like the power was obvious, but the sensation of lift, and just the overall smoothness of the water flow was noticeable. <\/p>\n\n\n\n
\u201cI could tell immediately that it was engineered to help all levels of swimmers get the most out of their workout.\u201d<\/p>\n\n\n\n
Swim spas combine the benefits of a pool with the therapy and relaxation of a hot tub. For triathletes like Hoffman, these swim-in-place pools can be a valuable training tool. You can swim on your schedule, work on your form, and make recovery a priority.<\/p>\n\n\n\n
However, when you are considering a swim spa<\/a>, there are several factors to weigh. You want to compare the swimming experience, along with the size, features, and how it will complement your backyard space.<\/p>\n\n\n\n Whether you are training for a triathlon or want an alternative to a backyard swimming pool, a swim spa takes the stress out of exercise and swimming. The water reduces the effects of gravity on your body, and the backyard convenience means that you are no longer double checking pool hours on the way to the gym.<\/p>\n\n\n\n A swim spa is an investment, and you want to feel confident that you are choosing the best swim spa for your lifestyle, space, and budget.<\/p>\n\n\n\n The H2X Challenger swim spa series<\/a> by Master Spas was designed to provide a quality swimming experience. The jetted system does not introduce air into the water current, creating a smooth, wide channel for swimming in place. There are three swim pumps, too, allowing you to adjust the power of the water flow.<\/p>\n\n\n\n Comparing these swim spas, you\u2019ll want to consider which spa should be strong enough to challenge you but also adjustable to your level of ability. <\/p>\n\n\n\n Master Spas unveiled the H2X Challenger series in 2019, redefining what a swim spa could be. Designed for athletes and fitness enthusiasts, the Challenger series delivers a powerful, smooth current for anyone looking to improve their swimming, build endurance, or simply enjoy the benefits of aquatic exercise.<\/p>\n\n\n\n While Challenger swim spas come in a range of sizes, the 15-foot model is a standout. It\u2019s spacious enough for serious swim sessions yet compact enough to fit in most backyards.<\/p>\n\n\n\n One of its key features is the six-jet swim system, engineered to create a strong, even current without air turbulence. By drawing and drafting water from multiple points, the Challenger 15D provides a smooth, predictable flow \u2014 so you can focus on your stroke without feeling disrupted by choppy water.<\/p>\n\n\n\n The Challenger 15D is powered by three motors, including two variable-speed motors, allowing you to fine-tune the current to your exact training needs. Whether you’re working on endurance, speed, or technique, this system delivers a swim experience that suits all levels. The redesigned Challenger series is now even faster than before, with a top pace of 1:10 per 100 meters.<\/p>\n\n\n\n Beyond swimming, the Challenger 15D offers exceptional hydrotherapy features to help you recover and relax. Whether you’re easing sore muscles from a tough workout or just unwinding after a long day, the spa\u2019s therapy jets target high-tension areas with a soothing massage.<\/p>\n\n\n\n Exclusive features like the StressRelief Neck and Shoulder Seat and Xtreme Therapy Cove provide targeted relief, while contoured seating ensures comfort. With the touchscreen control panel, you can easily adjust the water flow to create your ideal recovery experience.<\/p>\n\n\n\n The latest Challenger models continue to push the limits of swim spa performance, offering an unparalleled combination of fitness and relaxation.<\/p>\n\n\n\n \u201cI can tell you straight away \u2014 this thing is amazing,\u201d Ben Hoffman shared after his swimming in the updated H2X Challenger swim spa<\/a>.<\/p>\n\n\n\n The updated design and larger footprint provided the Arizona-based athlete with his best stationary swimming experience.<\/p>\n\n\n\n The 18-foot swim spa has three dedicated swim pumps, including two variable speed motors. An additional pump powers the hydrotherapy seats, including the exclusive Master Spas\u2019 StressRelief Neck and shoulder seat. <\/p>\n\n\n\n Most people will be able to swim comfortably in a 15-foot swim spa. However, taller swimmers might be more comfortable in an 18-foot model. The Challenger 18D has an increased swim area and a water depth of about 51 inches. <\/p>\n\n\n\n But the increased length is not just about having room to swim all four strokes.<\/p>\n\n\n\n \u201cI do feel that there is slightly less turbulence in the longer spa, and the water seems to circulate more smoothly,\u201d Hoffman says. <\/p>\n\n\n\n To maximize the water flow, Master Spas engineers relocated the pumps and returns. The design helps to increase the strength of the water current. The top-end speed of the H2X Challenger 18D Pro is 1:10 per 100 meter pace.<\/p>\n\n\n\n Hoffman swam and relaxed in an H2X Challenger 15D before upgrading to a newer model with a more powerful swim current. As a professional triathlete who swims about seven hours a week, he found that training in a swim spa was ideal for recovery swims, kick sets, and aqua jogging against the current.<\/p>\n\n\n\n With the redesigned Challenger series, Master Spas has made significant improvements to the swim experience. The upgraded variable speed pumps (VSP) provide a stronger, smoother current, making it easier for swimmers to fine-tune their training.<\/p>\n\n\n\n \u201cThe added power with the dedicated VSP jets gives the Challenger an edge when it comes to training at higher intensity for me,\u201d Hoffman says. \u201cI am able to do some longer threshold swims that help me simulate my IRONMAN pace.\u201d<\/p>\n\n\n\n One of his favorite workouts in the Challenger swim spa is a continuous swim effort with kick sets. An example would be to swim for five minutes and then, using a kickboard, kick for two minutes. Repeat the set five times.<\/p>\n\n\n\n \u201cAnother favorite is to program a build swim that might look like five times five minutes where speed increases from 15 to 25 by two each minute.\u201d<\/p>\n\n\n\n A standout feature of the H2X Challenger series is its balance of performance and relaxation. The advanced swim system allows for an uninterrupted current, while the hydrotherapy seating offers a place to recover post-workout.<\/p>\n\n\n\n For Hoffman, a father of two, this versatility makes all the difference.<\/p>\n\n\n\n \u201cIt has been helpful if my wife or kids want to \u2018join in\u2019 for my workout!\u201d he says.<\/p>\n\n\n\n Recreational athletes, weekend warriors, and anyone looking for an at-home swimming option will love the quality and adaptability of the Challenger series.<\/p>\n\n\n\n When choosing a swim spa, it’s important to consider your individual needs and preferences, including the size of your space, your budget, and your desired features. <\/p>\n\n\n\n Comparing the Challenger swim spa models, it will often come down to your space and lifestyle. Faster swimmers and those who want the swim spa to be the centerpiece of their training might prefer the 15-foot swim spa. A Challenger swim spa with a larger swim area might also be the best option if you or someone in your household is taller than 6-foot-2.<\/p>\n\n\n\n Recreational athletes, weekend warriors, or those who want an at-home swimming option will love the quality and versatility of the Challenger series. <\/p>\n\n\n\n \u201cHaving a tool like the Challenger that produces endless fun for your family and friends, but also gives you all the power you might need in your swim workout is the pinnacle,\u201d Hoffman says. <\/p>\n\n\n\n \u201cHowever, take a look at your goals, swim pace, and experience while deciding. They are both amazing options depending on what you are looking for.\u201d<\/p>\n\n\n\n Do you want to be able to swim, exercise, and relax at home?
