I highly recommend Altitude Athletic to anyone looking to level up their fitness. I first joined a friend and was surprised to see how dramatically different I felt training at altitude. After becoming a regular member it didn't take long to see improvements in my strength, cardio, and heart rate both in and outside of their facilities. The staff is knowledgeable and provides a supportive and encouraging environment for all of their members who are looking to achieve personal goals. The facilities are beautiful and the equipment is top notch. This is one of the few gyms I have found that has treadmills that incline to 25% (majority are 15%). This is one of the best gyms in Toronto. The fact that it's the only public gym to offer training at simulated altitudes is icing on the cake!
