WATCH: Cavinder Twins kick off summer with intense workout at Miami training facility

The Cavinder twins, Haley Cavinder and Hanna Cavinder, are not taking their return to college and the opportunity to play on the Miami Hurricanes basketball team lightly. The sisters are sweating it out at the University of Miami's training facility.

On Monday, the NIL superstars posted an Instagram video featuring their "first day of summer workouts" in their Under Armour OOTDs. Their day starts right from waking up and making their bed before enjoying the morning coffee. After giving food to their furry friend, Harvey, they took off to the university, having their breakfast on the campus.

The athletes then enjoyed the outside Miami weather, engaging in light running and conditioning exercises. Then came the energy drinks, after which the real hustle started—the weightlifting session. After that, the twins had their lunch prepared by Chef Nicole. Have a look at their day:

Secret behind Cavinder Twins' NIL success

Haley and Hanna Cavinder have mastered the art of name, image and likeness success. Their journey began when NIL regulations were relaxed in 2021, allowing athletes to sign endorsement deals.

The sisters quickly capitalized on this opportunity, leveraging their immense popularity on social media. When asked about their rapid rise during an appearance on "Overtime" in 2023, the Cavinder twins shared their approach.

"When NIL was passed in 2021, nobody knew what to expect," they said. "Our minds were just like, let's have fun and make videos together."

This spontaneous and authentic approach struck a chord with fans and brands alike. The twin sisters also emphasized the importance of surrounding themselves with the right team:

"Our agency does a good job at meeting long-term brands and getting equity in businesses, giving us creative control, which we love."

Taking a year-long break from college, the Cavinder sisters focused on building their personal brands, collaborating with several major companies amid a stint with WWE. The twins boast a combined NIL value worth an impressive $2 million (as per On3).
