I was searching for a way to calculate calories burned during footbag.
Found this site.......that actually had "hacky sack" listed as an activity.
For folks tracking diet and activity, this may help.
Check it out!

Just realized, I started using SparkPeople to track diet and exercise a few days ago, they too have hacky sack listed as an activity.
Nice thing about SparkPeople, it is free and they have an android app which seems to synch with the online account as well. you can set goals and it tells you what you need to do to get there. Also, it tells you your daily breakdown of calories, carbs, protien, and fats and how many you have remaining to meet your goals. Seems to also take into account your activities when determining your goals.
