One of my goals is to increase endurance. At first I struggled to get through a 15 minutes dance video. Now it seems to go by fast and lately I can do two of them in a row so 30 minutes of dancing. Today I got about 34 minutes of dancing, four just focused on arms. I have the desire to use dumbbells and stuff too. I need to get more. I only have two 2lb and one 10lb. Miss that with the gym the most.
