Swim workout 6

Less drowning, better form today. Little by little I feel like I am understanding how to do this. The program Hines has here is pretty smart: we are still doing all of the balance exercises for a lot of sessions. Like every exercise activity, I think the trick over the coming weeks will be to stick closely to his program---although individual laps got my HR up and left me short on breath, my conditioning level is such that the 1/2-hour in the pool was by no means exhausting. I ended up adding an extra 2x25 swim to this mix. I suppose that it is accurate to note that the RPE was probably a 4

Hines gives us a lot of credit for the vertical kicking that I am not sure we are due. Even with the additional 2x25 swim at the end, I swam 30x25 or 750 so the 4 VK sessions are presumed to add 150 yards (which seems high to this novice)--if this was really 'like' an 850 workout, then even with my additions, we are looking at a length for each VK which is probably something like accurate if a little high. The main issue for me is getting to a point where I can swim a mile or two without feeling that I am going to die.
