Reply To: Target time for 100Free LCM
Compromise with him, and give him a little more rest so he can do more reps at the faster pace. How would he do at 13.25 if you set the interval at 35 instead of 30? If he can’t do many reps at that, then try 40 seconds.
In my (admittedly limited, sample size of 1) experience, “specificity” overrides all other factors. When in doubt, swim faster and adjust the other variables to accommodate.
