Renava is a personalized 90-day posture training app designed to help you improve your posture, build better movement habits, and support your body after long hours of sitting, working, or looking down at a phone. Start with a short onboarding, and Renava creates a posture program based on your answers, goals, available time, and the areas you want to focus on — such as your neck, shoulders, upper back, chest, or core. Your main plan is built as a structured 90-day program divided into three 30-day phases. Each phase gradually guides you through posture-focused exercises, mobility work, stretching, and body-awareness routines to help you move better and build a more consistent posture habit over time. After the 90-day program, Renava continues with a maintenance plan designed to help you keep your progress and support your posture long term. Each daily session works like a guided workout: • Clear video instructions • Exercise-by-exercise guidance • Timers and rep counters • Step-by-step movement flow • Simple sessions you can complete at home Choose the session length that fits your day: • 5–8 minutes • 8–12 minutes • 12–15 minutes You can also add extra routines alongside your main plan, including morning mobility, evening stretching, gentle recovery, and calming movement routines. Inside Renava, you can: • Follow a personalized 90-day posture improvement program • Build better posture habits step by step • Get guided exercise sessions with video instructions • Focus on neck, shoulders, upper back, chest, and core mobility • Add extra morning, evening, stretching, and recovery routines • Track your streak, completed sessions, minutes, and exercises • Unlock achievements and follow your progress over time • Continue with a maintenance plan after the first 90 days Renava is built for people who spend long hours sitting, working at a desk, using a laptop, or looking down at a phone. The goal is to make posture training simple, structured, and easy to repeat every day. Renava is focused on general wellness, posture awareness, mobility, and movement education.
