Cardio focus and heart-rate zones
Your last 4 weeks split into low aerobic, high aerobic and all-out work, with a plain takeaway, like base building or a good mix.
- Zones your way: share of max heart rate, heart-rate reserve, lactate threshold, or your own
- Time in each zone for every workout and the whole day
- Plan by distance: pick a run, walk, ride or hike and see the time and effort from your recent workouts
