Rainy day cardio suggestions?

mistifiedrt

Hey there! So I've been doing great on getting outside everyday that I'm not working of going to the park and doing a 3 mile run/walk and have been feeling great. I also do my 30 day shred. Anyhow, today it is gloomy and rainy. I don't have a gym membership and live in a small apartment. I'm looking for ideas to get my heart rate up and some cardio in despite this weather. Any ideas?
