I'm not the greatest swimmer, I usually get out the water just after 1/2 way in the Tri's I do, and typically do sessions like 15 to 20 x 100 with10 sec rest in the low 1:40s, or 400s around 7:00 with 15sec rest.
When I first started out I did some swimming with a Pull Buoy and was lots quicker with it. recently I've been reading a lot that folks do pull bouy and paddle work. Today I did some 200s alternating PB and non PB and was ~5sec quicker on average without it. So I must now swim with a better body position or kick than I used to.
Why do folks train with a PB ? is it to recreate a wettie swim position/style ? and should I be doing some PB swimming ? When I first used it when I was a novice, it made me loads better but I stopped using it as I was worried it would become a crutch and I'd be carp without it,
I think that using paddles is no go as I only swim during public swimming times and then arn't allowed then.
