FAQ – Kaehler Core (KC)

  1. Can a shorter person use a KC that is sized for someone who is taller? Yes. While the handles will be further away from the shorter user you can simply pull down on the moving tube with your hands until you can grasp the handles.
  2. Can a taller athlete use a KC that was sized for a shorter athlete? Yes, however they taller athlete will not be able to reach full arm/ leg extension when doing squatting exercises or when doing floor exercises where the feet are locked in (knees to elbow or squat press).
  3. Can I exercise on the KC by gripping the moving tube instead of gripping the handles? Yes. This is actually a great way to work on a larger grip hold compared to the handles, which offer a smaller grip.
  4. What areas of the body does the KC train? It trains the whole body. The KCs unique design allows you to resistance train in both directions for any exercise movement. This means that you can set-up resistance in a pushing and pulling direction for the same movement pattern. Visit our suggested exercises links to target muscle groups and specific sport related training.
  5. Can I use the Kaehler Core inside my house? Yes. If your KC is 94 inches or less you can do all exercises in a home with 8-foot ceilings. If you have a KC unit longer than 94 inches you will need to do the standing squat exercises outside or in an area in your house that may have higher ceilings like your garage. Many KC exercises are done on the floor or at an angle so ceiling height is not an issue.
  6. What is the difference between the fixed KC and the split-couple KC? The split-couple KC breaks down into two pieces for easy travel and storage and weighs about 3 1/2 lbs. more than the fixed KC, otherwise they are exactly the same.
  7. How much does the KC weigh? The fixed KC weighs 13 pounds. The split-couple KC weighs 16.5 pounds.
  8. Will I get injured training on the KC? The KC was invented by a world-class physical therapist, Bob Kaehler, to prevent and eliminate injuries and he has helped thousands of athletes and patients optimize training and recover from injuries. The resistance bands are gentle on the joints and deliver a powerful strength training effect without the harsh impacts on your joints or back from convention weight and exercise machine training. Please consult your medical physician before starting any training program.
  9. Will I get sore using the KC? Like any form of exercise you may initially be sore in your muscles when first starting out. Unlike free-weight or machine training with weights, the resistance bands don’t cause significant damage to muscles (sarcomeres). If you don’t have the strength, you won’t be able to move the tube if the resistance is too heavy.
  10. My joints often get sore when I try and squat with free-weights will the same thing happen when I squat on the KC? Squatting on the KC actually unweights your joints as you drop down into a squat as you have to “pull” yourself down under increasing band resistance.
  11. My back gets tight when I lift weights will this happen when I train on the KC? The KC actually will help build a stronger, more powerful, and pain-free back that will actually help you feel energized following training, not stiff and tight.
  12. Are the feet difficult to secure to the KC? At first it will be a little bit of a challenge to get the feet secured into the KC but after a few sessions it becomes easier. Our product design team is exploring a clip-in option similar to cycling, although with cycling sandals for better exercise stability, clip in, and quick release.
  13. Can I train on the KC anywhere? Yes. You can train on the KC at the beach, in a park, at your home, at the gym, even in space. If you have a split-couple KC you must dry off the split-couple if you get it wet as it may rust.
  14. Can I get the KC wet? If you have a fixed KC you can train on it anywhere, even in water as all the exposed fixtures are stainless steel or powder coated steel. It is highly recommended you towel dry the KC and leave it in a dry, warm area immediately after it is exposed to water. If you have a split-couple KC, take extra care to dry off the split-couple as it is manufactured from high quality steel that may rust if exposed to water.
  15. Can I take my KC with me when I travel for business or vacation? Yes, if you have a split-couple KC it can be broken down for easy travel. For flights you can check it on a luggage like golf clubs or skis.
  16. What is the best way to carry the KC when I travel? We are in the process of making a prototype travel bag for the split-couple KC. We are hoping to have them in production sometime in the summer of 2018.
  17. How hard is it to store the KC? The split KC breaks down into two pieces with the longer base measuring about 55 inches. When the handles and foot boards are disassembled, the KC fit foot print is 55 inches x 8 inches x 5 inches.
  18. Who can use the KC? The KC is currently being used from athletes as young as 13 years-old to others in their 60s, 70s. We even have a KC athlete who is 87 years old who trains on it several times per week.
  19. How many different exercises can I do on the KC? We have documented more than a hundred different exercises on the KC. We know there are many more waiting to be created. If you have specific, targeted muscle group development or needs in mind, please explore our website or reach out to us to help you get the most out of your KC experience and to help us expand our available exercises.
  20. Why do I have to buy a split-couple KC if I am over 6’ 2” tall? Recently Fedex and UPS raised shipping rates (4 to 5x more) on boxes over 96 inches long. We can ship fixed KCs up to 94 inches long as it fits in a 96 inch box. For athletes taller than 6’2” in height the split KC is really the best option due to increased shipping cost. A $50 shipping charge on a 96”box (or shorter) goes to about $220 if the box is over 96” long. KC sizing for athletes over 6’2” cannot fit in a box 96 inches or shorter. We can accommodate your request if you prefer the fixed KC with its higher shipping cost.
