Which is better, step aerobics and Spinning (cycling)?

Question

Please post up the positive AND negative sides
such as.. which gets leaner muscles, burns more calories, etc...

If I were to choose an-hour-long class every other day
which should I take?

Answer 1

OK, I'm not wild about either of them. I find step aerobics too hard on my knees (but I have a bad knee) and spinning bores me silly (but that's just me).

Positives:
Aerobics is more of a total-body workout while spinning is mostly lower-body.

Spinning likely burns more calories - but it will depend on the class.

Spinning is easier on your joints.

Negatives:
Aerobics requires more co-ordination

Spinning can be hard on your lower back if you don't get the bike adjusted just right.

If you're going to do an hour-long class every other day, why not alternate and do both (step on Monday, spin on Wednesday, step on Friday...)
