You can do this balance exercise just about anywhere. This exercise is laced-into the Health & Wellness workout on the Hawk Trail (Post 6b). You can also easily integrate this exercise into any other workout. On the trail, be on the lookout for fallen trees or rock groupings, like those found in dry riverbeds. In a more urban environment, be on the lookout for parking curbs or lines along the sidewalk that you can follow.
A Joint Strengthener
An added benefit of this balance exercise is that it will also strengthen your ankles, calves and thighs; as there is some correlation between balance exercise and strength training exercise.
Perform 2-3 sets of the exercise for 60-90 seconds; and build up from there.
