Renfort: Back & Neck Coach

Stretch & strengthen in 10 min

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Mira, your AI coach, guides 10-minute sessions for your neck, back and shoulders. New: live duels, hold a plank against a friend, each at home. Renfort helps you loosen up and strengthen your neck, back and shoulders in 10 minutes a day, at home or at the office. Mira, your AI coach, guides you by voice from start to finish: she introduces each exercise, reminds you of good form and cheers you on. Every move is demonstrated on video with a big, clear timer, so you can do your session without breaking position to look at the screen. MIRA REMEMBERS A 15-second check-in before your session (where it feels tight, how much discomfort, how much time you have) and Mira suggests the right session, even a 3-minute express version. Day after day, you see what works best for you. CHALLENGES AND DUELS • Live duel: challenge a friend right now or at a time you choose. Same position, each at home: the first one to let go loses. • #BeatMira: every Monday, Mira sets a time. Beat her and share your score card. • Timed challenges: plank, wall sit, glute bridge… beat your personal best. 6 PROGRAMS • Stability: shoulder blades and rotator cuff • Release: neck and shoulders • Upper back: rows and stretches • Lats: strengthening and stretches • Glutes: pelvis and hips • Flexibility: hips, hamstrings and back WELLBEING Guided breathing, relaxation with music, seated massage, active desk breaks, posture, sleep, anatomy, and an "In the car" session to do while parked.
