Are You Over Doin IT

First, yes it is bad for your body.Your not giving your body enough rest. Your rest days which are saturday and sunday should be spread inbetween the exercise days.Monday and Tuesday seems fine. But im worried about thursday and friday since they take up a huge amount of time and are right after each other thus, not giving your body enough rest to grow and to properly help your muscles work.This could lead to overworking which would give you problems.I suggest changing your schedule if possible
Try this
Monday - Yogalates + Thai Bo --> total 1hr 20minsT

Tuesday - Latin cardio + step class --> 1hr 50mins

Wednesday - yoga + total tone + hip-hop dance -->2hrs 45 mins

Thursday - RestFriday - pilates +step class + kickboxing --> 4hrs

Saturday: Rest
Sunday: 1hr Street DanceBut, i think its better if you just completely remove one of those exercises.
For example removing street dance, will give you an extra day of rest.

Monday - Yogalates + Thai Bo --> total 1hr 20mins

Tuesday - RESTWednesday - yoga + total tone + hip-hop dance -->2hrs 45 mins

Thursday - RESTFriday - pilates +step class + kickboxing --> 4hrs

Saturday-RESTSunday-Latin cardio + step class --> 1hr 50mins

Try as much as possible to alternate exercise days and rest days, it would do you much better than exercising everyday and resting on sunday when you dont need rest since you've rested on saturday
