Real-World Adaptations
Here's how 12345 Boom handles common scenarios.
You missed yesterday's workout
We analyze if it was a key session. If so, we reschedule it. If not, we absorb it and move on—no guilt trip.
You went on a surprise 80km bike ride
We detect it from Strava, calculate the training load, and adjust tomorrow's hard run to an easy recovery session.
Rain forecast for your long run
We suggest an indoor treadmill alternative, or help you swap with another day this week when weather is better.
You rated your last workout as "felt terrible"
We reduce intensity for the next few days and add extra recovery time. Your body is telling us something.
You're training with kids this week
We provide modified workouts: shorter intervals, playground-friendly exercises, stroller-compatible runs.
You PR'd your 5K in a training run
Congrats! We record it, update your training zones, and adjust future paces to match your new fitness level.
