To get in extra fat burning time I now use a timer and set it for 2 minutes and do walking lunges as well as other full body workouts.
If you spend a lot of time sitting at a desk it's helpful to have a timer that you can set so you get up every hour and just dance for 2 minutes.
I like to do deep lunges but if you're wearing a skirt that can be tough. It's so important to get up and move a lot during the day!
