In general, when I swim with a group, I notice that I usually am at the front on kick sets without fins. When, however, we have sets with fins, I usually fall behind. Why is this?
The other day, I was swimming with the high school group and they were begging to do a 10 x 100 kick with fins on 1:10. No way could I make this. When I suggested doing 10 x 100 kick on 1:45 without fins, nobody thought they could make it. In fact, the coach gave a small set of 100s on 1:45 that was without fins and I thought it was pretty easy while the others could barely make it.
In any case, why do I stink on fin work when I am a pretty strong kicker without the fins? Is this a bad thing?
