Hi Raynor,
I was wondering if you have any insight, or can direct me to the correct place to learn about optimal heart rate zones for cardio training
For example, I understand there to be 3 exercise zones, fat burn, cardio and peak. I like to train for intensity so I am always in the cardio-peak zone, I run 5 days most weeks, right now treadmill bound until the winter lets up.
Anyways, my goal is to drop body fat, and simultaneously improve my speed and endurance
Right now, my schedule is as such:
Sunday- Endurance run (I add 5 minutes to this run each week, I started doing this at the start of February and I'll cap out at 60 minutes next week- currently at 55 minutes). I'll start at a comfortable speed, which was 6.3 MPH just yesterday and then I increase the speed every 3 minutes by .3, I got up to 8 MPH and for the last 5 minutes I started going down in speed
Monday- off
Tuesday- Interval training, 40 minutes, 10 minute warm up 1.20ish miles usually, small progressive increases. Then 30 minutes where I'll do 9.0-11.0 MPH for 1 min/walk at 3.5 MPH for 1 minute- I feel like I can push the speed more which I might start doing this week
Wednesday- 40 minute endurance run, same format as my Sunday right but always 40 minutes
Thursday- Interval training (same as Tuesday, 40 minutes)
Friday- Off
Saturday- Interval training (same format as Tuesday/Thursday)
If it matters, all runs are being done fasted. I do engage in intermittent fasting for my diet. I take a BCAA shake prior to my runs as well as a caffeine pill.
I do have a FitBit and I log all my runs and I'm just curious, what is the most optimal heart rate and how long should I be at peak, or cardio heart rate for my runs?
Is there anything you would change about my regiment? I plan to add incline probably starting March or mid-March, I'm just working on continually getting faster first
All the best
Aerobic, Aerobic-Anaerobic, and Anaerobic are the three zones you are talking about.
Aerobic is around 50-65% of your HRR + RHR (heart rate reserve and resting heart rate)
Aerobic-Anaerobic is around 70-85% of your HRR + RHR
and Anaerobic is around 85-95% of HRR + RHR
HRR = max heart rate minus average resting heart rate. Example, if your max heart rate (220 - your age, or literally figured through cardio trials) is 190 and your resting heart rate is 50, your HRR is 140.
Plug that number in and you will get 50-65% of 140 (70-91 + RHR [50]) = 120-141 BPM. That would you be the ideal zone for fat burning.
Aerobic = best overall fat loss
Aerobic-Anaerobic = best overall for fitness
Anaerobic = best overall for pure cardio and carbohydrate depletion
In general, for a rule of thumb, 120-135 bpm is a gold standard for most people when doing cardio. The caveat is HIIT (high intensity interval training) which has been shown to be more efficient at burning fat and increasing cardio endurance rapidly.
