Is it OK to train in Zone 4?
Is it OK to train in Zone 4? For those wishing to increase fitness or lose weight, exercising in heart rate zones 3 and 4 is sufficient. Such exercises are referred to as aerobic and should be undertaken 3-5 days per week in order to build strength.
Why is it so hard to stay in Zone 2?
Zone 2 running is “hard” because most people find it very challenging to stay at a slow pace for a long time. 45 minutes should be the minimum time that you should aim for. Until your aerobic base (and mitochondria) are better trained you will find that you have to run at a painfully slow pace and walk many hills.
Is it good to be in Zone 4?
Higher zones like 4 and 5 help to develop efficiency, burn the most calories overall when comparing short bursts of time, but are zones we can sustain for the shortest amount of time. Zones let you know how hard you are working and what energy sources are fueling your workout.
Is Zone 3 or Zone 4 better?
Physiological adaptations are similar as mentioned above for Zone 3, just even more so, especially the ability to clear lactate. Intervals in Zone 4 can really improve your lactate threshold and help you either go faster or closer to your threshold for longer.
