Great app series
From training for pull-ups crunches sit ups or whatever other work out you may use Runtastic does a phenomenal series of applications. I use it when I go cycling I use it when Im working out around the house and I find it keeps me just as motivated as going to the gym. A+. Recommend the series of apps to anybody who wants to get in shape or stay in shape!
