Question

You want to aim for a maximum heart rate split in each set

what does ''split'' mean in this sentence ?

Answer 1

It makes no sense.

A split time is the time taken to complete a portion of the complete exercise. If you are running say, a marathon, you might be interested in your split time at each mile marker for example. Think of splitting the whole time of the exercise into smaller parts.

Heart rate is, as is explicit in the term, a rate. A count of something, in this case, heartbeats, per unit time, in this case that unit being a minute. You cannot 'spilt' a rate.

Take out the word split and it makes sense - you want to reach your maximum heart rate in each set i.e. go all out, don't mess about, this isn't a cooking class, put your back into it son!
