"It's Hot Summer Nights. Plan to be hot, definitely," Jennings teased. "I'm gonna give the people what they came to see."
The football star is holding his own among the pro dancers as they hit the road for two months, performing 46 shows across the U.S.
"It's an honor," Jennings said of performing side-by-side with dancers like Sharna Burgess, Sasha Farber, and his DWTS partner, Emma Slater. "They're so good at what they do. In certain ways I feel like an equal, but it's really humbling."
But while the dancing is new for Jennings, sequins are not.
"[I felt comfortable wearing sparkles] probably about like, 15 years ago," he revealed. "I was suggesting these things. I'm the type of person that likes to see, 'What can I get away with?' So being on this show allowed me to express all that."
While Jennings dazzles on the dance floor, he'll also be keeping up with his football training, continuing his daily three-hour workouts as he hopes to get picked up by an NFL team.
"In every city I'm going to have a different gym," he said. "I'm not going to miss a beat."
And though Jennings is clearly pressed for time, he's not looking to speed up his love life with a run on The Bachelor.
