I go to the pool nearly everyday, and I swim laps (25y lengths, 50y laps). I noticed that swimming 10-12 laps (250-300y) doesn't really tire me out, so I can do it daily. But, swimming a mile (33 laps, 1650y) does tire me out, so much so that I need to rest for a couple days (1-2). The two patterns (~11/day and ~33/ 3 days) have the same daily lap average. Which is better for me? 11 laps per day, or 33 laps one day with a 2 day break?
My guess was (Because it takes about 3-4 days for the microtears in muscles to rebuild) that the 33 laps is better than the 11.
