Brain
NeurocognitionCross-body movement, reaction work and mental tasks while moving. Goal: attention, concentration and mental clarity.
B⁴ App
Doctor-designed neuro training for posture, mobility and focus.
The B⁴ App is the training app of B⁴ Neuroperformance, the institute of PD Dr. med. habil. G. Ama K. Finjap, neurosurgeon, in Neustadt an der Weinstraße. It brings your personal programme to your phone in short guided video sessions. We do not only train muscles. We train control by the nervous system.
10 to 20 minutes a day is enough. Available in English and German, for iPhone and Android.
The app combines movement, coordination and body awareness. Every exercise comes as an explainer video and as a follow-along repetition video. Your plan is built after a consultation at the institute or by video, and adjusted continuously based on your feedback.
It is designed for adults who want prevention, guided continuation after physiotherapy or rehab, better posture and mobility, or sharper performance in daily life and sport.
Why neuro training?
Movement starts in the nervous system.
The muscle executes, the brain controls. When you trip, brute strength will not save you; control and timing will. That is why many B⁴ exercises are easy for the body and demanding for the head. That is where the training effect lies.

How it works
Short sessions, steady feedback, a plan that keeps changing with you.
Daily rhythm
Watch the explainer once, then follow the repetition video. Activate in the morning, release in the evening. Five short sessions a week beat one long one a month.
Feedback
After each session you rate the exercises and report changes. The team uses that feedback to adjust your next recommendations.
Support
The app includes chat with the team, appointment booking, an exercise diary, reminders and a growing knowledge library.
