H2L Cycling Instructors

Meet Adam

Cycling Instructor HeadshotThe Facts: Adam Castner is a Schwinn Certified cycling instructor at H2L Studio. He works as an employee benefits consultant (Insurance Broker for employers).  He lives in Mechanicsburg with his wife and 2 children.

His History: Adam spent his early years heavily involved in football and wrestling in the Mechanicsburg school system.  He then attended Bloomsburg University where he wrestled on their D1 program and also met the love of his life (Charity Castner – Yoga instructor at H2L).  After college, there was a major gap in consistent exercise in Adam’s life.  His wife signed him up for our 2016 Cycle Relay benefiting MASH Mini-THON and he was compelled to go to cycling classes so as not to keel over and/or highly embarrass himself.  However, after a few classes, he fell in love with the indoor cycling classes.  In less than a year he decided he wanted to get certified and help teach and encourage others in this fun and challenging activity.

“I tell people all the time now that there are so many positive aspects to indoor cycling and specifically with the H2L system that you need to check it out (3 times at least).  It is a plug and play model, you don’t need a partner, you don’t need equipment, there is no program you have to worry about or track and, most importantly, you don’t need to be at a particular fitness level to do this activity.  You just show up, sit on the bike, and work as hard as you can.  There is a great level of energy and adrenaline to help keep you focused and working hard.  The instructors guide everyone through the class, encouraging you, as well as, instructing.  The nice part is, if you’re unable to perform at a high level, it’s ok, as long as you are working hard for YOU and pushing yourself you will see results and have a great experience.  Furthermore, with the H2L system you can see your cycling statistics, not only as you go, but immediately after class, they are sent to you.  So, you have the data on your ride without doing anything but showing up and working.  Try that in a traditional gym!  I have lost 20 pounds, in less than a year, simply by going to this studio 3 times a week and pushing myself.”

What to Expect: Through Adam’s class you will be challenged and encouraged.  He will help you to dig deep and find a little more effort to give.  Musically, there will be a diverse mix of songs to accompany the journey and enhance the class.  The goal is to help you walk away having worked harder than you thought you could work while having a great time doing it.
