Like black holes, children grow rapidly, have seemingly bottomless appetites, and were frequently used to complicate the plots of Shakespearean tragedies. Set your tot twisting with today's Groupon: for $30, you get a 10-class kids' Zumbatomic punch card at Elite Pilates Reformer Studio on Stone Oak Parkway (a $100 value). Classes will be held Monday–Thursday from 3:00 p.m. to 3:45 p.m. or from 3:45 p.m. to 4:30 p.m.

Elite Pilates Reformer Studio's instructors employ more than 25 years of Zumba and dance experience to keep kids fit and active. Designed for tykes ages 4–12, Zumbatomic classes set energetic movements to the rousing strains of kid-friendly hip-hop, reggaeton, and cumbia. Staff scale choreographed routines to the smaller limbs and advanced wall-bouncing skills typical of fledgling humans to boost confidence, stoke metabolisms, and build coordination. At the end of each month, Zumbatomic participants showcase their buffed-up rhythmic sense in a dance performance for an audience of parents and top Zumba critics.
