Gym class (open)

Tsubaki made it to gym class and got changed barely on time for warm ups, this consisted of 5 minute run around the gym, stretching, and about 20 push ups, but again, that was just warm ups. By the time the main unit of the class was reached tsubaki was more than wiped out.
"goodness...huff..huff..I think..huff..huff..there trying to kill me!" tsubaki said to herself as she considered this possibility.
