The kingdom of your ruler Jupiter includes health, and while he may not be the most romantic planet in the heavens (he has other gifts), you can combine fitness with a little one-on-one time to strengthen your bods and your relationship!
Try some circuit training. If you each pick two moves and both do all four, you can lift weights together, but go at your own speed.
Do as many reps of each move as you can in one minute, and keep it up for 15 minutes. You can challenge each other, so long as you don't overdo! Treat yourselves to smoothies at the juice bar afterward!
