This is what it looks like when you prepare intensively for your comeback! We will miss @alexzverev123 a lot at the @usopen , but the @daviscup in Hamburg will be a special day! Sascha trains extremely hard and also uses improVR glasses in the rehab process. We visited some sessions in Monaco with @skysportde . The final video will be available soon - stay tuned! _ #goimprovr #improvingathletes #alexanderzverev #alexzverev #saschazverev #zverev #tennis #atp #atptour #usopen #rehabilitation #rehab #recoveryjourney #recoveryispossible #recover #athletedevelopment #virtualreality #vrexperience #vrglasses #vrbusiness #virtualrealitytraining
