The AlterG uses advanced differential air pressure technology to generate a powerful lifting force, which provides precise unweighting in 1% increments from 20% of body weight up to 80% full weight. The athlete wears custom neoprene shorts and zips into the airtight chamber. The chamber becomes pressurized and calibrates to your exact body weight allowing for total control over the amount of weight bearing.

I know what you’re thinking: “Why would I want to run indoors when it’s finally nice outside?!” Just hear me out and you’ll see how it will enhance your outdoor runs and races.

Meet Patrick – he’s been a LiquidGym staffer for over 2 years. And he’s also a triathlete. A really, really good triathlete. As in, he completed his first year as a U23 elite by finishing 10th at Nationals. Patrick uses the LG facilities because they are a great training tool for conditioning and injury prevention.

This is Patrick running on the AlterG Anti-Gravity Treadmill. Did I mention that LiquidGym has the only AlterG in Ottawa? That’s part of The LiquidGym Advantage. But I digress.

That day, Patrick’s coach had advised him to get in a 40-minute run on a soft surface. Why or what is a soft surface, you ask? Anything like a dirt trail, gravel or grass; something not as hard as sidewalks or roads to minimize risk of injury while maintaining milage. That’s crucial as Nationals are only a few short months away. As an alternative to a trail run, Patrick was running on the AlterG with only 70% of his body weight. And it’s much gentler on the joints when you unburden them from full body weight.

Another benefit to AlterG training is on the conditioning side – you can increase your pace while reducing your body weight. Your legs can train at a faster pace while running at 80%-90% body weight and get used to moving that fast. Translate your training on the AlterG to outside, and you’ll be able to hit your speed more consistently on race day.

If you want to train 7 days a week on hard surfaces, you risk injuring yourself. A run on the AlterG keeps you running injury-free. So, do you AlterG?


What’s a runner’s high? If you’re a runner, you know. It’s that amazing feeling of “psychological well-being” you get during or after a run.1When a runner gets injured and can no longer run, they miss it. A lot. That’s what happened to LiquidGym member Sylva when, in 2013, she suffered a stroke that completely paralyzed the right side of her body. An avid runner and yoga instructor, Sylva first had to relearn simple tasks like writing and walking. Her progress was slow and frustrating; all she wanted to do was don her runners and hit the road.

Fast forward to late 2015, when she discovered LiquidGym. Sylva was still limping, her right leg was still weak and she was swinging it to walk. She joined LiquidGym and began walking on an underwater treadmill 5 days a week. Every lunch hour, she’d be there – walking, then running, forwards, sideways, backwards – strengthening her muscles and retraining her brain to work with her body. Her balance improved tremendously from working out in the water.

Last month, she added 2 weekly sessions on the AlterG Anti-Gravity Treadmill: 3 days a week in the pools, and 2 days a week on the AlterG. She wanted to add more weight to her body during her workout – in the water, she’s chest-deep, so she’s only working with 30% body weight. On the AlterG, she’s now working with 80% bodyweight. The addition of the AlterG to her training has resulted in huge improvements. Sylva was seeing tremendous improvements – her gait was even and she wasn’t swinging her leg anymore.

Sylva’s goal is to run again. With LiquidGym, Sylva feels that she’ll achieve her goal. When asked for one word to describe her experience with LiquidGym, Sylva said “amazing”. But she didn’t stop there: “Being a runner, the biggest benefit is mentally. It’s priceless that I can run again. LiquidGym allowed me to run again. In the water for past few months, now I am working toward running on the AlterG and I am very close. Next step is running outside again and I know with LiquidGym and my persistence I will get there. Once a runner, always a runner. Thank you LiquidGym!”
