Kelly Coffey Meyer is putting some workouts up on youtube now .....you may want to check her out. Lots of good content on youtube I find. Equipment, no equipment etc. There's Barlates/Linda Wooldridge, Fit Body by Julia, Fitness Blender, shortcircuits by Marsha, Mike Donavanik, Group HiiT, Shelly Dose, Eye See Digital, Michelle Lumadue (some quite long workouts) BeFit, NewDay4Fitness, Fitness by PJ, AngieFitnessTV (good step), eFit30, FemFusionFitness (not traditional workouts, excellent for pelvic floor stability) ....just to name a few. The streaming I have done in the past are Cathe of course, Sleek Technique (loved it, made my waist look amazing, but FAR too costly), FitnessGlo (no longer available, really liked it though. Lots of solid instructors, all workouts about low intermediate to high intermediate) and Pilates on Fifth.
I honestly do not know if there is anything comparable to what Cathe LIVE does. Especially with the whole group dynamic going on. Daily Burn maybe. Or Les Mills. Have not tried those out.
