Hi, I'm Justin Gauthier
Canadian-born and raised, I obtained my Bachelor of Science in Human Kinetics (the study of human movement) from the University of Ottawa in 2009.
I have coached & personal-trained clients for the better part of 15 years. My specialty is water-based exercise and my level of expertise is wide-ranging. Today, I'm here to help you along your recovery and re-conditioning journey! Movement is Medicine and you deserve to live life to its fullest!

Don't sit idle. Move your body.
Why Join My Program?
Movement is medicine and water healing! Water is the perfect environment for movement & exercise. KneeFlex 8 will help you re-gain strength, joint flexibility and optimal range of motion to get you back on track & living your fullest. Grease those gears!
Plus, the water's hydrostatic pressure and buoyancy will help you with pain management and improve blood flow to speed up recovery. You'll also see results in overall full-body fitness & core strength, flexibility, walking gait, posture, and balance. All to say: I'll get you back on track so you can keep living life actively and to the fullest!
KneeFlex 8 - Coming soon!
I'm on a mission to help you achieve faster and optimal recovery & re-conditioning so that you can keep healthy and active. Don't let the weight gain creep up on you! My upcoming 8-week program is carefully crafted using water-based exercise as your next step to an optimal & active lifestyle after your knee-replacement surgery.
You may have already did a short course of physiotherapy immediately after surgery, and so this is your next step! Don't stop now...I designed KneeFlex 8 to be highly effective for continued strength & flexibility training that also targets full body conditioning too. It's easy to follow along and when you keep consistent with my program, I guarantee you'll see real timely results - confidence boosting improvements in strength, range-of-motion and functional locomotion, as well as total body fitness.
Wake up each morning with peace of mind that you're taking care of what matters most - your optimal self! Don't sit idle!
increasE mobility
Active movement in the water has been shown to be an effective way to increase joint range-of-motion and muscle flexibility.
Build strength
The natural properties of water provide exercise resistance, similar to the gym. The resistance such as downward movements against buoyancy strengthen muscle and bone.
Build Aerobic fitness
Water aerobics exercises build your stamina. By increasing your aerobic output in the water, you'll help strengthen your heart and lungs for everyday living.
manage pain
The water provides a natural cushioning for your joints and helps to reduce physical pain while you workout. Hydrostatic pressure improves circulation & reduces swelling.
improve balance
Moving through water requires more effort, engaging your stabilizing muscles such as your abdominals and spine-supporting back muscles necessary for good balance.
Keep low impact on joints
Water submersion reduces weight-bearing on joints & allows them to build strength without the added stress, especially after injury or surgery.
My 8-Week Program: KneeFlex 8
In my 8-Week Program: KneeFlex 8, I'll show you all the right moves to get you off the ground and into the pool in no time! Specifically designed for recovery & re-conditioning following a total knee replacement, my program will guide you through all the necessary exercises to get you back on track. My program is divided into three stages (Early Stage, Intermediate Stage, Advanced Stage) where I will guide you along toward optimal recovery and total body fitness.
KneeFlex 8 is adaptable to your level of fitness and swimming ability. Each exercise will be demonstrated by simple and easy-to-follow instructional audio format using a water-proof headset as well as videos that you can watch before you hit the pool or bring along with you to the poolside with a smart phone or iPad. I've designed this program with simplicity in mind to make your workout fun & effective!
Get Stronger
Use the natural properties of water to build your strength while keeping your environment lower impact on your joints.
Musculoskeletal Re-Conditioning
Take the stress away from on-land weight-bearing exercise & use the properties of water to re-gain your strength & range-of-motion.
Build Stamina
The water is naturally a more challenging environment to move through & exercise requires more aerobic work. This builds your aerobic capacity.

What Makes My Program, KneeFlex-8 Different
The human body needs to move as it was meant to. Movement is essential for a healthy body & mind. As we age, movement becomes increasingly precious & we need to keep oiling that machine (the body) for continued functional & active living.
Our joints work hard for us and in return, they need us to move them to keep them strong & flexible. Not moving leads to a terrible outcome: body de-conditioning and health decline in all measurable areas.
Water-based exercise helps eliminate the tradeoff between the demand on our joints and exercise. KneeFlex-8 is designed for continued aftercare post-knee replacement, but it goes a mile further to also work on total body strength & mobility too.
Frequently asked questions
I recommend having some swimming and floating ability for your safety in the water. Many exercises will be performed in chest-deep water as well as deeper water for suspension exercises. Flotation devices can be worn for added security.
The water is a cushioning workout environment that reduces impact on bones and joints. Water-based workouts are effective and help eliminate the risk of joint injury.
I'm currently building interest in my program. My program is aimed to launch by Spring of 2025.
I have taught aqua fitness and aqua therapy programs for more than 15 years. My experience ranges from class instruction to 1-on-1 personal training sessions.
Some pools use salt water which tends to be better on your skin. You may consider looking for local pool facilities that are salt water. Special moisturizing soap when you shower afterwards is also a good idea, followed by a thick body moisturizer. Water-based exercises can also be done in natural bodies of water as well as natural pools.

It sure is! You can increase or decrease your workout intensity by simply lowering the speed of movement in the water. In the water, the faster you move, the more resistance you'll encounter and that can be dialed down to a more manageable pace.
That's not a problem. You likely have a community pool in your local area. Find out what times are available for public leisure swims (note: it might be a good idea to call and find out what times are available to do exercises on your own).
KneeFlex-8 was designed to help you recover and recondition after your knee-replacement surgery. It's always a good idea to first check with your doctor and make sure you are cleared for any exercise program. The water is in fact the best place to workout if you have any artificial joints as the environment will be low-impact.
Be sure to first check with your doctor before starting any workout program. Community pools have lifeguards on duty who are trained in first aid, CPR, and defibrillation. Typically, the water is a cooler workout environment that helps to keep heart rate lower as you workout too!
The recommended water temperature is on the warmer side to help with muscle relaxation (between 84 and 90 degrees Fahrenheit) however a cooler temperature below 84 degrees is still effective especially with this style of program that incorporates circuits into each workout. Avoid very cold pools below 80 degrees.
