I love this app/service!
I log into daily burn on my iPhone for a quick 15-30 minute workout on my lunch break or on the web page at home i will sign in anf log Longer workouts like tabata or yoga. I love the db challenge feature because the program keeps track of your personal best and most recent challenge scores. Other than kinect fitness which I also use but doesnt travel well, this is the most fun and responsive way for me to workout. Also love the db15 series and am working my way up to the inferno series.
