Questions about workouts

I have been doing workouts on my own and am confused on some of the drills: 1 x 100: +15 1 x 75: + 10 Thanks Could I get a little more context on this? Maybe post a little more of the set? Looking at this, my best guess is that it's swim a 100, take 15 seconds rest, then swim a 75, then take 10 seconds rest but that doesn't make sense based upon the above.

Hello, I was a competitive swimmer in high school and just coming back to the pool after 13 years of being out of the water. I just joined Masters and so I am late catching onto some of the terminology. I have been doing workouts on my own and am confused on some of the drills: 1 x 100: +15 1 x 75: + 10 I guess I am old school but I don't even remember this in high school. Someone help!!! I need a good website that explains terminology and sets etc. Thanks most likely the +15 is the amount of rest.

A lot of , on written sets wil see rest time as " R i " OR "on " and then a time

I think that's correct. The workout board at my pool always puts "R" after the distance, but I think the + does mean stopping for that period of time.

Hello, Sorry I think I was vague. I pulled this off some of the workouts I have been doing. So here is an example: MAIN SET: 1 x 200: last 50 Catchup +10 1 x 300: last 50 Catchup +15 1 x 400: last 50 Catchup +20 1 x 500: last 50 Catchup +25

Yeah, best guess is the +10, +15, etc. is the amount of rest to take after each swim before starting the next one.
