If you "like" your created workout, you can use a pc to go to Skimble.com and delete it, which frees up the slot to create a new one (it might take a few hours for the system to register that its deleted) but then, I _THINK_ that the without you created and liked will still be under your "liked" workouts. Its weird but true for me so far. Two workouts I've created and deleted still appear under my liked workouts with somebody named "Craig C" as the creator.

Yeah it let me create three too, before, but when i deleted one to make another it wouldn't let me..until I deleted another. So now i have two and if I hit "create workout" it gives me the go pro page...so hehe yeah "two or three" is the official answer

Lol OK man at least now I know not to delete one

If you delete it, make sure to like it first, you MAY still be able to have it in your liked list and keep doing it.
