Choosing Non-Impact Workout Options

Choosing Non-Impact Workout Options

Every week, several people email me about cardiovascular options other than running.  Running is a great cardio option however, if your knees are injured, you are overweight, or just need a break from running for a while, here are some non-impact cardio options that I prefer to do:

Swimming Options

Water is a domain that very forgiving to the joints of the body.  If you are able to swim, the workouts below are a great way to build up your heart and burn calories.  These are quick and easy workouts as well as very advanced workouts that I do not recommend doing alone or without a lifeguard.  If you are a beginner, do what you can and it maybe necessary to learn a few techniques to swim more efficiently.  I learned by watching swims teams practice, but there are many videos and swim instructors out there to help you.  If you are ever in the Maryland area, I teach swimming / workout for free for military / law enforcement / fire fighters.

Quick Workouts 300m timed swim plus 5 x 100m sprint

200m warmup 10 x 50m sprints (rest 30-45 sec) 500m cooldown

Repeat 5 times Sprint 100m-200m tread water 1 min (no hands)

Medium Workout 20 x 25m sprints rest 10-15 seconds   10 x 50msprints rest 20-30 seconds

100m Pyramid Swim 100m keep pace between 1:20-1:40 for all Rest 30 secs Swim 100m Rest 30 secs Swim 100m Rest 30 secs Swim 100m Rest 30 secs Swim 100m Rest 40 secs Sprint 100m - ______?

repeat in reverse order but rest with 50m slow swim / breastroke / back stroke etc...

Longer Workout 500m warmup 5 x 100m sprints 5 x 50m kickboard 5 x 50m arm pull only Swim 500-2000m with fins or without fins non-stop

Prep for BUDS 1 mile swim with fins or 2 mile swim with fins

Getting Harder Hypoxic Swim 100m 4 strokes / breath Swim 200m  - 6 stroke / breath Swim 300m - 8 stroke / breath Do PT for 5 minutes (pushups / abs) Swim 4 x 100m at 8-10 strokes/breath rest 30 seconds each 100m Do PT for 5 minutes (pushups / abs)

Hypoxic Workout Swim 300-500m - 4 stroke per breath - 6 stroke per breath - 8 strokes per breath  total distance 900-1500m

Keep going if you wish then repeat in reverse order (rest optional - 20-30 secs in between). You should strive for around 1000m

One of my favorite bike workouts is the stationary bike pyramid.  You can actually do this on an elliptical machine as well.

Bike Pyramid:

Start - Level 1 on manual mode for 1 minute and keep the RPMs at 80-100.  Each minute that passes, increase the resistance by 1 level.  Continue this process until you are having difficulty breathing and/or peddling.  When you get really good at this you can take the bike to level 20.  THEN, repeat the cycle in reverse order.  So you have a warmup - max out - cool down all rolled into one nice package.  This workout will take 39-40 minutes if you are that advanced.  But, if you can only get up to level 10 and back to level 1, your time investment is only 19 minutes.  I do the same on an elliptical machine but find that increasing by 2 or 3 levels each minute makes it more challenging.  Also a SPINNING class at a local gym is a killer workout is one of the best ways to burn calories with a group of people.

Of course, getting outside on a real bike can be another way to get cardiovascular workouts.  Make sure you have a safe place to ride like bike trails versus sharing the road with vehicles.  Save that for the more advanced riders.  There is a new piece of equipment called the Elliptigo that is an elliptical machine but placed on a bike frame.  Pretty cool - check out the site.


If you have never ridden a rowing machine - also known as an ergometer, let me tell you - it is tough and a great full body workout.  I always wondered why so many guys who rowed for their sport went onto SEAL training and did very well.  It is one tough cardio-vascular exercise.  My swim buddy Alden Mills of fame was team captain of the Navy Heavyweight Crew Team and at 230 lbs could crank out 30 pullups.  That is what rowing can do for you.  But if you are seeking just a great non-impact cardio exercise, rowing maybe right for you. The good thing is that the machines like Concept 2 or Vasatrainer have programs on the machine that challenge you and keep your interest.
