I do a buddy training session for two women (same age), and both women wear heart rate monitors during the session. Both clients have their age, height, weight, gender, and resting heart rate entered in to their HR monitors. At the end of a 30-minute session, Client “A” has burned 475 calories while Client “B” has burned only 320 calories. Client “B” is frustrated because she did the exact same work out as Client “A” and did not burn nearly as many calories. Based on the HR monitor readings, Client “A’s” max HR during the session was higher than Client “B’s.” Does this mean that Client “B” is more fit than Client “A” and that it is going to take more exertion for Client “B” to achieve the same calorie burn as Client “A?” Is Client “B” not working as hard as Client “A,” even though Client “B” feels like she worked as hard as she could during the workout? Could it be possible that both clients are equally fit and one just has a physically bigger heart than the other?
There are so many variables with this. It could be that that possibly Client A is fitter and has more efficient muscle tissue than client B, or their heart rate monitors are not calibrated to match each other, or, Client A has already done exercise prior to your workout and will then burn more calories than client B, or, Client A is working harder than client B
When you say Max Heart Rate, do you mean, Optimum?
My thoughts are mixed with this question.
I don’t like having my clients “compete” with one another, we all work out differently
Also, Heart Rate Monitors are only a part of the equation,. I would also go by waist/hip measurements, or skin fold measurements
I suggest having them switch heart rate monitors and see what happens.
