Well…how much can you handle? We have found the minimum number of classes to come to per week to see results is three or fours classes per week. On the other hand, you have Firebreathers like Sam who came to both the noon and Level 2 workouts today! Obviously not everyone will have that kind of work capacity (nor is it normally recommended), but the consensus definitely is; the more effort you put in, the more you get out.
