I have loved Orange Theory these last few years, but the treadmill stuff is getting really hard on my legs and lower back, and I'm annoyed at the overabundance of arms and lack of focus on core. (I'm 50, and I need my core development.)
Orange Theory has kept me hooked with its rigorous routine, fun music, accountability model (no refunds if you miss the class you signed up for), and variety. Can anyone suggest a fitness place that has something similar, preferably in Upper NW? I want to work up some dopamine and sweat and muscles!
