Planks Work for Me

Haven't done zumba this week, not sure it works for me... time wise it's a 90 minute process and I don't have 90 minutes that I want to devote to one day of exercise. What does work is planks. I've done planks Tuesday, Wednesday, and yesterday. Going to do them again today. It's just 12 minutes to strengthen, tone and define. Diet is going well. I think I'll lose weight better by focusing on diet and not worrying about cardio, more than if I did cardio and didn't eat well. Once the weather warms up I'll be happy to go for a run, but until then, I'm just going to keep cleaning the house and being up and busy all day, with planks to top things off.
