How to Read a Swim Workout

How to Read a Swim Workout

Many beginner swimmers set out with a goal of swimming a half mile or a mile straight through. I cringe when I hear that—it’s not really the best way to do a swim workout. If you were lifting weights, you would do 3 sets of 10 repetitions of a biceps curl, instead of 30 straight repetitions, right? The same goes for swimming.

Swim workouts are generally written in “sets” of yards or meters, depending on the pool you are working out in. Workouts are broken into sub-groups, to focus on different aspects of your fitness and swimming.

Good swim workouts usually have this general setup:

Warm Up:

  • Purpose: to prepare the muscles to exert themselves.
  • Percentage of total distance: 10-20%
  • Exertion: similar to a slow walk

Drill Set:

  • Purpose: reinforcement of one or more aspects of a stroke so that proper form
  • becomes ingrained action
  • Percentage of total distance: 5-7%
  • Exertion: medium

Kick Set (legs only):

  • Purpose: leg strength
  • Percentage of total distance: 10%
  • Exertion: depends on the set

Pull Set (arms only):

  • Purpose: shoulder work, upper body technique
  • Percentage of total distance: 20%
  • Exertion: depends on the set

Main Set:

  • Purpose: cardiovascular/strength/power
  • Percentage of total distance: 35-45%
  • Exertion: depends on the nature of the training that day

Speed Set:

  • Purpose: maintenance of power
  • Percentage of total distance: 5-10%
  • Exertion: all out

Cool-Down:

  • Purpose: allow the heart rate to slow down gradually, allow the shoulders to
  • stretch, avoid pooling of blood
  • Percentage of total distance: 10%
  • Exertion: similar to a very slow walk

Here are a few sample sets:

3 x 100 freestyle on 2:00

Do not “do the math” and swim 300 yards straight through. That will not accomplish the purpose of the set. This set means that you have two minutes to swim 100 yards using freestyle stroke. That two minutes includes your rest time, so the faster you get it done, the more rest you get. After that two minute time period, start another 100 yards. Repeat 3 times.

4 x 50 choice of stroke, with :15 rest

This would mean that you swim 50 yards with whatever stroke you want, then rest 15 seconds and start again, for a total of 4 times. Again, do not do the math and swim 200 yards straight through.

Below is an example of an entire workout:
