What if I sign up for 4 days and want to add more?

No problem.  If you sign up for the 4, 8 or 12 days and decide to add extra days, you may purchase single classes for $30.00 each.  This option is for current boot Campers only.  If you are not enrolled in Boot, you may not purchase single classes at a time.  It's a program, not just a single workout.  There is method to my madness.  :-)
