Last week's swim was another challenging one that separated the pull and kick a lot. I like this for strength and form work, and have really noticed a difference when you put the whole stroke together. The warmup was 900m of swim, pull, kick and a bit of I'M and I thought I was in trouble as I just couldn't get my timing down for any stroke. A bit of pull work fixed that up, and then it was on to the main set.
The set was quite like a ladder- 300m kick, 200m pull, 100m I'M, 200m faster pull, 300m faster kick. The kick went well and reinforced my form. I find when form gets sloppy my legs threaten a cramp when I am wearing the fins. You can't muscle through it with those fins on, so you learn proper technique. When it came to swimming the full (free) stroke; I had an easy and efficient kick again.
Fins do beat the crap out of your legs though, in a good way. There are a lot of muscles that get activated with the fins and I do like it. This wll certainly help the bike and run strength too.
