Kyle Kratzke stepped outside his apartment to get on a bus — a bus transformed into a yoga studio. It's called the "Elevation Station."

"I'm going to learn yoga poses and relaxation techniques," Kratzke told NY1.

He had a rare brain tumor when he was six years old.  

"It was a really hard time, eventually I got through it. It affected my learning, processing things. Emotionally, I was having some issues, too," Kratzke said.

He says in the past year heading to the Elevation Station has done wonders for his health and well being.

"These poses have helped my balance. Being diagnosed with a brain tumor, I don't always have the best physical use of my body," Kratzke said.

Yoga instructor Karisa Johnston had a brick and mortar studio, but knew she wanted to help people who couldn't always get to her class. On this day, her bus was parked in Flatiron.

"I kept going to bed and waking up every morning thinking how can I help the people who are not as mobile as everyone else," Johnston said. "And that was when I developed the Unum Heart Elevation Station, which is the bus we are in now."

Johnston said her method of teaching yoga and calming the central nervous system helps her students with and without disabilities.

"Wanting more balance in your life, wanting a quick tool to release a daily stress," Johnston  explained.

The other student at this class, Lauren Bianco, is learning a technique to prevent anxiety.  She says the mobile classes have helped improve her mobility. 

"This has really helped me balance my emotions, help me with my anxiety, social anxiety and helped me with my balance,"  Bianco said.

Johnston has had the bus for five years. Her next goal is to have buses like it all throughout the five boroughs."

As for Kratzke, he looks forward to many more stops in his neighborhood.

"It really helped me feel more relaxed and good about myself," Kratzke said.
