WHY THIS WORKOUT

Sunday’s 5K intervals and yesterday’s lower-body session are already in your week. An easy run keeps you moving toward your 5K without adding another faster session.

See what informed this
  • 5K intervalsA faster running session is already part of this week.
  • Lower-body strengthYesterday’s lower-body work counts alongside the running.
  • Steady rideAn hour on the bike adds to the week’s overall movement.

Also included: 28-day totals, your 30-minute window, and your 5K goal. No current soreness or race result is included, so this example uses effort rather than a pace target.

In Dark Flow, each recommendation is saved with the context used and its explanation. You choose what the AI receives. The original workouts stay intact.
