Hikes got you weak in the knees? As much as we love a good hike, without proper recovery, they can cause some pesky knee pain. This active recovery class reduces tension and restores energy in the hips, legs and lower back. Begin with seated leg stretches (both held and dynamic), move into an active lunge series and wind down with supine openers. This sequence is great after a hike or any other lower-body intensive cardio workouts.
