This feature requires an active KAYA PRO Performance or Outdoor subscription.
Since KAYA already connects you with the climbs available at your gym, your Smart Logbook can recommend actual climbs there, shown as Suggested Workouts under the Summary tab (tap the plus button at the bottom of the app, then Summary). Suggestions appear after you've set a goal, checked in, and completed a session, they're built for your next session based on how the previous one went.
Depending on your goals and current form, a suggestion might help you warm up progressively, build power or endurance, practice a specific movement style, find climbs near your current grade, or just have a varied, engaging session.
