Abs are getting stronger

I was too sore on Sunday to do anything. I could barely walk. So I decided to work on abs and do planks. Most fitness instructors will tell you that you need to hold a plank for two minutes. I am not there yet. I was able to hold it for 1 minute and do another rep for 45 seconds and 35 seconds. I then did v ups, side planks (2) and scissor kicks. I am getting better each week and today's test will be to see how much I can run – I may just do treadmill work for 20 minutes. Each day I see progress and it is motivating.
