Much like swimming, aerial yoga is a no impact activity that lets you move your body in completely unique ways without creating any joint impact. You can even perform cardio exercises to increase your heart rate without any impact and from a new direction, which automatically boosts your workout.
Rev up your endorphins with aerial yoga. Inversions have a way of boosting the mood anyway, so add the ability to move like a trapeze artist and succumb to some old-fashioned whimsy, and you will likely experience an endorphin bonus.
Inverted postures are very helpful to strengthen and balance the spine and the core. Instead of shying them away, do attempt them.
