NFL superstar Rob Gronkowski will join tennis star Venus Williams to lead their fans in a free at-home workout on Friday, April 24, at 12 p.m. EST.
The session will be hosted by Williams on her Instagram account. The tennis champ has made her daily training sessions must-stream events during the quarantine period, using the tag #CoachVenus. She's done workouts with supermodel Naomi Campbell, comedian Amy Schumer, her sister Serena, and more—fellow tennis pro Grigor Dimitrov even made news when he flashed his abs in their session. Now, she's going to put Gronk to the test for a "Flex Friday" workout.
