I am looking for a plugin and wondering if you all knew of one that would perform most or all the functions below.
I have a fitness website and I am want to begin offering 30 day fitness challenges to my users. I am looking for a plugin that would allow users to enter the number of minutes, reps, etc. of a particular exercise they do each day for 30 days. It would track each users activity level until I begin a new 30 day challenge. It would also have a leaderboard that would show who the top performers are.
