Jenna Dornseif instructs the following:
  • CYCLE + CORE
  • Its all in the name. Half cycle, half core burning! BOOM...  designed as a sweat-fest combination of intense cycle conditioning followed by core isolating moves to improve stability and posture leaving you with a tight and toned midsection!

  • BIKE & BARRE Express
  • Our normal Bike & Barre class but all fit into 50 minutes!
    Build endurance, strength, and long lean muscles. Dynamic cardio sequences get your heart pumping on the bike and at the barre, targeting the seat, legs, abs, and arms, for sculpted and elongated muscles and a trim and toned physique. There’s never a dull moment as you hit maximum calorie burn - zoning out is not an option.

  • CYCLE
  • NOT another spin class…Hop on a REBEL CYCLE for an unpredictable, challenging and fun ride full of hardcore interval drills mapped for endurance, power and speed.
