Whether getting back into yoga after an extended hiatus or working with physical restrictions, the Wonderblock makes more positions possible. And compensates for injury and arthritis to keep practitioners moving through the entire class. EVA foam grips the floor well on extended, off-mat positions for confidence-building security. Active Junky first tried this yoga block on a retreat in the mountains of Utah. As an easy-washing option to other products, Wonderblock’s smooth domed top and utility in every configuration make it a winner. Even if the goal is harmony, not competition.
