Safely Exercised

I went to Finley, I just could not stay away from the pool. I wore the b70, no problem and does it help with dps.
It went like this, very cautious, only a few strokes of 1 arm
500 easy swim
500 kick with fins
10x25 kick with board dolphin/flutteer
10x25 breast turns, tread water in middle of pool for start 1 min
10x35 free turns, tread water in middle of pool for start 1:30
1750 yards plus treading
