Zone 2 at age 58 explained
Zone 2 is easy, conversational aerobic exercise — the intensity that builds endurance with little fatigue. It is usually defined as 60–70 % of maximum heart rate. Because max heart rate falls with age, so does the Zone 2 range. At 58, the Tanaka equation estimates a man’s max heart rate at 167 bpm and the Gulati equation estimates a woman’s at 155 bpm, giving the ranges above.
Individual max heart rates vary by 10–15 beats around these estimates, so treat them as a starting point. If your breathing feels laboured or you cannot speak in full sentences at the top of the range, you are probably above your personal Zone 2.
All five heart rate zones at 58
| Zone | % max HR | Men | Women |
|---|---|---|---|
| Z1 Recovery | 50–60 % | 84–100 bpm | 77–93 bpm |
| Z2 Aerobic / Easy | 60–70 % | 100–117 bpm | 93–108 bpm |
| Z3 Tempo | 70–80 % | 117–134 bpm | 108–124 bpm |
| Z4 Threshold | 80–90 % | 134–151 bpm | 124–139 bpm |
| Z5 VO2max | 90–100 % | 151–167 bpm | 139–155 bpm |
Zone 2 by resting heart rate (Karvonen)
The Karvonen method uses your heart rate reserve (max minus resting), which accounts for fitness. Find your resting heart rate — measured in bed on waking — in the left column:
| Resting HR | Men (Zone 2) | Women (Zone 2) |
|---|---|---|
| 50 bpm | 120–132 bpm | 113–123 bpm |
| 55 bpm | 122–134 bpm | 115–125 bpm |
| 60 bpm | 124–135 bpm | 117–126 bpm |
| 65 bpm | 126–137 bpm | 119–128 bpm |
| 70 bpm | 128–138 bpm | 121–129 bpm |
| 75 bpm | 130–140 bpm | 123–131 bpm |
How to train in Zone 2 at 58
- Make most runs easy: for most runners, three or four Zone 2 sessions a week plus one harder session is a sound structure.
- Go by effort on hot days and hills: heart rate rises with heat and gradient, so slow down or walk to stay in range.
- Track progress: note your pace at the middle of your Zone 2 range once a month — it should get faster as aerobic fitness improves.
- Add strength and recovery: from your 50s onwards, strength training and extra recovery days help you keep training consistently.
Health first. If you have a heart condition, take medication that affects heart rate (such as beta-blockers), or are new to exercise, ask your doctor which heart rate range is right for you.
