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.

About

Zone2 Autopilot

Features
Read full description

The usual way to ride Zone 2 is a fixed power target, but fixed watts can't account for how your heart rate responds or drifts as you warm up and tire. Zone2 steers by heart rate instead. It adjusts your smart trainer's power in real time to help keep you inside the Zone 2 band you set - no FTP test, no workout to pick, no numbers to chase. Press start and pedal. As an early tester put it: "That was my best Zone 2 workout ever. No joke. I get distracted and usually end up way too high." What you get: - One-tap start after setup - Automatic trainer adjustments to help hold your saved heart-rate band - Live cadence with a spin-up nudge when you start to grind - Time inside your saved Zone 2 band to see how much of each ride stayed in range - Auto-pause and resume when you stop and start - Works with FTMS smart trainers that support Bluetooth ERG target-power control, plus Bluetooth heart-rate straps (developed and validated on a Wahoo KICKR and Polar H10) - Apple Health sync - No trainer yet?
