You show up to the gym, don't have a plan, do a short warm-up, and go straight to projecting. Sound familiar? Flash Forward changes that. Flash Forward is for climbers who want to bring structure to their training. Whether you're following a coach's program, a published plan, or your own system, the app gives you a simple way to build sessions once and execute them in the gym. Open the app, hit start, and follow your plan. Build sessions from scratch or customize from a library of climbing-focused defaults. Mix on-the-wall and off-the-wall training in the same session, and pull from a broad exercise library covering strength, calisthenics, and flexibility. Set sets, reps, load, rest times, and RPE as precisely as you want, or keep it simple. Flash Forward is the only climbing training app where you can combine warm-up, strength, flexibility, and on-wall routines in a single session. Edit reps, sets, load, or swap exercises mid-session, without stopping or restarting. Just adjust on the fly based on how you feel that day. Train with purpose. Climb higher.
