Heart Rate Training
Hello there! Today I am checking in regarding workout intensity and heart rate training.Essentially, when you workout with Workout On The Hill, you are moving between three energy systems: phosphagen, anaerobic and aerobic. The phosphagen system is the first burst of energy in a lift - it can last form 7-11 seconds, the second energy system, the anaerobic system kicks in when you are lifting weights or doing metabolic conditioning, past the 7-11 second mark, and your heart rate is elevated. This means you body is drawing the majority of its energy from blood sugar, and possibly catabolizing some muscle mass for fuel. The aerobic system is the system you use for a moderate run, with your heart rate fairly low. You typically metabolize more body fat, along with oxygen to fuel this energy system. Recent studies show that higher heart rate cardio and metabolic conditioning are more effective at burning fat and increasing your fitness level that long duration steady state (strictly aerobic) cardio.
Each of us has a different target heart rate based on our age, fitness level and personal physiology. If you are on a beta blocker, the entire equation changes, because you literally cannot elevate your heart rate, no matter how hard you are working - this is dangerous - and requires that you keep your level of exertion under control.
Here is a simple heart rate article and calculator:

While I know my target heart rate, and I use a heart rate monitor sometimes, I also know what my rate of perceived exertion is (RPE):

While HR monitoring is more scientific, and RPE is more subjective, I think they both are valuable tools in determining how hard to work. I typically will spend no more than 28 minutes total per workout at a RPE of 7-9 - this 28 minutes "on" is not continuous, there are breaks, I am referring to total number of minutes "on" per workout, and a workout may be 45-60 minutes in duration - this is because my sport revolves around 5-6 minute bouts of intensity. During that RPE of 7-9, my HR might be 180-190bpm. These numbers might be too high for the general population, but they can be scaled accordingly.
The easiest way to translate the science is to take your pulse when you wake up, and plug that number into the calculation chart. When you workout, choose the intensity you desire, based on your goals, and make sure your heart rate matches the proper percentage for those goals. If you are experiencing incongruities, factor in your RPE, and adjust your intensity accordingly.
