Would it be possible to allow for a more customizable workout? It looks like the slider for Duration has limited choices: 10 minute intervals until you reach 40 minutes and then the only choice for the upper range is 100. This brings up too many workouts to look through. Any possibility you could include a way to enter a custom range, like 40 - 55?

Same issue with Calorie Burn. If I want to burn at least 200 calories, my choices are either 150 or 225. More flexibility here too?
