I'm 65: Is working out 4 days in a row (~3000, mostly moderately intense) ok? Even if times on repeats get slower on day 3&4, in long term does this strengthen conditioning? Or is it any way deleterious. Facts as well as opinions welcome! Tx.
I think there is so much individuality to have a rule. If your heart rate returns to baseline in about 4 hr and your sleep is fine it is probably not deleterious. In terms of strengthening conditioning, again, there are too many variables to be sure, but do you find the workouts challenging?
I will say, if your goal is to swim faster (or really since you are 65 decrease the rate of swimming slower) you should do some race pace work.
I found for myself, at about 73 I could only do 3 race pace workouts/wk without breaking down.
