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!

  • CYCLE45 + CORE
  • This 45-minute carefully choreographed rhythm ride is high-intensity ride set to the beat of the music. Challenging and fun, combining hills, flats, and sprints for an excellent cardio-focused interval training workout with some sneaky core moves on the bike. The finisher will be 10 minutes of off-the-bike core burning and strengthening!
