I was confused by the iver rides…. is that a kind of spin?
Once a week I do a kitchen sink class. I do not do a lot of this kind of class anymore, so I mix it up a lot, just to keep a hand in, and stay fresh.
One part I mix up is the music. I have done salsa, big band, broadway, eighties pop…. You do not say what your demographic includes, but I have a very mixed age group, and they seem to like it. It might not work as well with a very young group.
I like to start with floor cardio, move to step cardio, step with weights, and then weights. Sometimes we leave something out and add balance, or some power moves. I like squats with the step, and we sometimes do balance, or core work.
One set I like is to do is push up series. I start with flys. If anyone cannot do the push up due to shoulder, wrist, etc, they can stay with the flys. Then I do low plank with knee variations: stay in low plank, hold a small ball between the calves, just above the ankles, or a yoga block, and alternate lifting and pointing the feet. move to keeping knees together (loose the ball obviously) and alternating pointing toe to ceiling with knee bent. Then I follow with some prone back extensions and stretches.
do you do yoga? There are a number of strength postures that can well be adapted to such a class. Look up utkatasana and try it on the toes… but make sure they keep their knees behind the toes.
We also sometimes do slow and fast day…. doing a quick low impact run at random times, or a half time squat… just mixed in
