Good Morning America—November 16, 2017
How do identical triplets respond to different workouts? ABC’s Good Morning America turned to HSS exercise physiologist Polly de Mille, RN, MA, RCEP, CSCS, USAT and HSS sports performance specialist Jason Machowsky, RD, CSSD, RCEP, CSCS to help conduct fitness tests on Andrea, Arianna and Athena.
"Your fitness is not just how fast you can run. It’s how strong you are, how flexible you are and how well you can put that all together into movement. So we’re trying to capture all that," said de Mille.
To measure their baseline, the triplets visited HSS and performed tests in strength, functional mobility and aerobic capacity. The VO2 Max test, which measured aerobic capacity, recorded the amount of oxygen the body was able to deliver to muscles for energy production.
Next, the triplets went off to their assigned workouts (hot yoga, spinning and interval training), for classes four times a week. After two weeks passed, they returned to HSS and had their fitness levels measured again. The results were revealed to the triplets live on-air.
Athena, who did hot yoga, saw significant improvement in her core strength and functional mobility as she became more flexible after her workout routine.
