Clinic was excellent , Brenton attention to detail is second to none, extremely professional and technical, my son certainly improved his technique and incorporated the lessons learned from the drills to improve his breathing, body alignment and catch. Not only recommend but will get Effortless Swimming to film my son in about 6/8 weeks to monitor his progress. He managed to be just 1s off his 50m freestyle in the first lap of his 400m free today at a club meet. Thanks Brenton
