Zone 2 and Zone 5 Training
Summary
There are 5 training zones
Target zone 2 for aerobic performance and fat burning
Target zone 5 for VO2 max performance (if you can do this safely)
Heart rate is a common way to estimate which zone you are in
Maximum heart rate is determined by taking 220 and subtracting your age
For example, if you are 45 years old, your maximum heart rate is 220 - 45 = 175 beats per minute
You can use an aerobic machine heart rate measurement or a wearable to guide you
You can also look at the speed or wattage you are achieving on your aerobic machine while wearing a heart rate monitor so you have an idea of where your zone 2 is (but your zone 2 wattage may change over time or if you are tired or sick).
Zones
Zone 1: Recovery Zone
Heart rate target is 50-60% of maximum (e.g. if 45 years old with a max rate of 175 beats per minute, heart rate is between 88 and 105 beats per minute).
Zone 2: Aerobic Zone
Heart rate target is 60-70% of maximum (e.g. if 45 years old with a max rate of 175 beats per minute, heart rate is between 105 and 123 beats per minute).
You can talk sentences but with some difficulty
Aim for 20+ minutes (ideally 30-60 minutes) 3-4x/week
Zone 3: Tempo Zone
70-80% maximum heart rate
Zone 4: Lactate Training Zone
80-90% maximum heart rate
Zone 5: VO2 max Training Zone **speak with your healthcare provider before doing this training
Heart rate target is 90-100% of maximum (e.g. if 45 years old with a max rate of 175 beats per minute, heart rate is between 158 and 175 beats per minute).
This is near or at your maximum effort
Do this once per week (you can add it to the end of a 30 minutes Zone 2 workout). Warm-up before doing zone 5 training
Sample workout protocols for zone 5:
i) 30 seconds of full effort followed by 5 minutes of rest. Repeat 4 times
ii) after warming up, do a) 2 minutes of maximum effort and take note of how far your went (e.g. 600 meters); rest for 2 minutes; then b) go as fast as you can to make it to the distance you did in part a (e.g. 600 meters) even if that takes you longer (note the time); rest for 2 minutes; then c) go as far as you can in the time it took you to do part b; then cool down
iii) 3 minutes Zone 2 followed by 1 minute full effort, repeat for 20-30 minutes
