It’s a portable wall that uses “wheelbarrow” technology to make it easily adjustable and adaptable to the demands of your training session. It is the perfect tool for coaches, freeing them to give feedback to their players, instead of having to focus on serving or feeding balls into play. It can also be utilized for reaction training for goalkeepers. The SR has a thick, smooth, tough surface that enables a solid kick back when played against this portable wall. You can easily adjust the angle or distance of the Rebounder to increase the challenge.
