It is always good, if you swim every day, to have a workout that stretches you out, but doesn't kill you. Rest is just as important as working hard. Now if you are only working out once or twice a week, you should be getting all the rest you need and a workout like this one shouldn't be in your plan.
WARM UP--100 swim 100 pull
100 kick
300 yrds
1 x 25
10 sec rest
1 x 50
10 sec. rest
1 x 100
15 sec. rest
1 x 125
15 sec. rest
1 x 150 Kick
30 sec. rest
1 x 200
100 min. rest after this 200 swim then do this set backwards. This is called a pyramid set, you work your way up to 200 then back down to 25.
1300 yrds
TOTAL YARDS: 2100 yards
Warm Down with a long easy 500 yrd swim. Today is more of a rest day. If you have not done the previous days workouts and you feel you need a harder workout pick a day you haven't done and do it. Those of you that are training for a longer swim and only have two days a week to work out should not do this workout, but should pick a harder one earlier in the week.
