What workout should I choose for beach body workouts

Hello,

I recently got the Venu 3. I love it, but I'm unsure what I should choose for my beach body workouts. Most of them include weights, cardio, and aerobics like things. 

The Venu 3 won't let me just do a custom workout and send it to the watch. So I'm at a loss here. Before this I had a Fitbit and used just workout for my workouts. I'm new to all this.
