10*25uf (500/250u) = long fins (DYN), 25 under, 25 over, 3 breaths at the wall, 10 times
1*25ufufufufuf dnf (250/125u) = no fins (DNF), 25 under, 25 freestyle, 3-5 breaths at the wall, repeat 5 times
So when you do the 10*25uf - for the "freestyle" part are you using your arms and doing side breathing, and also fin kicking?
