Fartlek Training to Improve Endurance and Variety

Fartlek TrainingIs Fartlek Training for you…

Do you ever feel that the boredom and monotony of your cardio workouts is sapping your motivation?

Ever wish that your fitness routines weren’t always so structured and rigid?

Then this workout might be a great addition to your workout routines.

Fartlek training means “speed play” in Swedish, but it could also be named “variety play” – here’s why:

  • No set structure
  • No set rules
  • No pressure to follow a rigid routine

It was invented in the 1930’s, and has endured because of its effectiveness.

It is a form of interval training where you vary the speed of your runs between low and high intensity.  Fast runs and slow jogs.  Sprints and walks.  Work and rest.

Fartlek Training is Flexible

This is the beauty of fartlek…the routine is entirely based on how your body feels.  It is not a structured process like interval training.  It is up to you to stay motivated and focused, because the watch on your wrist does not tell you when to burst…your “insides” do.  (You can use your watch if you choose to be more precise).

This is why fartlek training is a great addition to your weekly workout routines.  It adds a little flavor to the process, and keeps things fresh.  All while adding nearly all of the benefits of interval training, and even HIIT, depending on your intensity.

You will only want to add 1 or 2 fartlek sessions per week to your routine, as the higher intensity requires more rest time (similar to interval training).

Benefits of Fartlek Training

Benefits of Fartlek TrainingThe benefits of fartlek training:

  • Add variety (and therefore a little fun) to your workout that will keep things fresh
  • Lack of structure so you can try different speeds, intensity, and routines
  • Your cardio heart rate will approach (or achieve) your anaerobic threshold and improve your anaerobic fitness
  • Includes speed work
  • Achieve nearly the same benefits as pure interval training (if you reach that higher intensity)
  • All terrains will work, as you don’t have to maintain a steady pace and you can do it anywhere – beach, mountains, fields, treadmills, tracks, and more
  • Avoids overuse injuries because you are varying the stresses imposed on your body
  • Increase your body’s strength and efficiency
  • Serious lower body workout that you won’t get jogging
  • Really burn the fat — much more so than steady state cardio

Warm-up and Stretching for Fartlek Training

Fartlek training, a form of interval training, is a very different workout than steady state cardio (long jogs).  So you need to be very cautious in your preparation for this training.

With higher intensity training, your hamstrings can give you fits. Your hamstrings can easily tighten up during sprints, and it can take days to work out the knots. This can be avoided with really heavy warm-up to make sure your muscles are very warm and ready.

Here is the warm-up suggested for higher intensity:

First, always make sure you are well hydrated. Dehydration contributes to muscle injuries and cramps, because it degrades muscle function.  If you go cocktailing the night before (dehydration), maybe stick with a long slow distance jog the next morning.

Step 1: Light Cardio to Warm Your Muscles

  • Jog in place
  • Jumping Jacks

Step 2:   Dynamic Stretching to Loosen Your Muscles

  • Lunges
  • Knee kicks
  • Arm rotations
  • Leg swings

Fartlek Workout Routines

Remember, fartlek is not a rigid and structured routine, but the routines below are a general guide – you can use LOTS of variation. Times below are only a reference…everything is determined by your fitness level and what your body tells you. Again, mix the times and reps as you see fit to experiment.

Fartlek training and interval training are not for beginners or those new to fitness and exercise. It is important to work up to this level – check with your doctor to confirm you are ready. If you can comfortably jog 2 miles at a 9-10 minute per mile pace, you are likely ready for some beginner fartlek routines.

Treadmill for Higher Intensity Workouts

When you adapt fartlek training for a Treadmill, but you have to be careful. If you try to adjust speeds on the treadmill while running, it can be dangerous – especially as you get more exhausted.

If you use treadmills often for HIIT and fartlek training, be very careful adjusting treadmill speeds (very distracting).

Treadmill Tips for Fartlek Training

  • Be very careful when you adjust speeds – dangerous and distracting
  • Make sure your shoes are tied very well, and you don’t have laces that might come loose
  • Stay focused on your space and speed, especially as you get tired
  • If you wear a walkman, watch the wires and keep your focus
