Understanding Spring Tensions

Springs on a Pilates Reformer vary depending on the manufacturer. Classical Reformers use springs that are all the same tension, whereas contemporary Reformers offer lighter or heavier springs indicated by colors.

Note that heavier spring tension does not indicate difficulty because many exercises require more strength and control on a lighter spring.

Understanding Spring Colors Across Brands

Classical Reformers: Gratz®, Techno®, Legacy®, Pilates Designs®, Contrology®, etc.

How to Set Up Your Reformer for Classical Workouts: Footbar, Gears & Straps or Ropes

The purpose of multiple gears and footbar settings is to adjust for different body heights and to make the tension lighter for some advanced exercises like Front Balance Control.

1. For Reformers that have rope risers: move the ropes to the bottom for classical workouts. Use the short loops for hands and long loops for legs, except for Short Spine which uses the short loops.

2. To find your gear/footbar setting: Lie down on the carriage with feet on the footbar, your hip angle should be around 90 degrees or slightly deeper with toes on the bar with heels lifted. If needed, adjust according to instructions below.

For height between 5’3”/161cm and 6’4”/195cm:
• Use the standard gear/stopper setting to achieve a 90 degree hip angle. (On a classical Reformer standard is: 1st Gear, the gear closest to the footbar. )
• If footbar is adjustable, try a setting that brings it closer to the carriage

For height under 5’3”/161cm – Move the carriage closer to the footbar:
• Use the gear/stopper closest to the footbar. The goal is to get the hip angle near 90 degrees
• If the footbar is adjustable, try a setting that brings it closer to the carriage. For Reformers with adjustable ropes/straps, after setting for a 90 degree hip angle, set the rope so the ends (not including handles or grommets) are 1.5”/3.81cm past the front of the shoulder block. Or when lying face up holding the handles with arms straight to the ceiling, the rope is lightly taught without engaging the spring
• A spacer box or block can be used in front of the shoulder blocks to shorten the carriage and allow the student to reach the footbar or blocks with the arms
• For the Short Box series: place the short box in front of the shoulder blocks instead of over them to bring the student closer to the footbar so feet can go under the footstrap. Be careful to ensure it is secure when getting on and off

For height over 6’4”/195cm – Move the carriage away from the footbar:
• Use a gear/stopper farther away from the footbar with the goal of hip angle near 90 degrees
• If the footbar is adjustable, try a setting that moves it away from the carriage 
• For exercises that push the carriage far from the footbar like Long Stretch, Semi-Circle or Short Spine shorten the movement to avoid hitting the back of the Reformer
• You may need to shorten the ropes/straps for a taller person to avoid ropes becoming slack. Lie face up on the carriage holding the handles straight up to the ceiling over the shoulders. The rope should be lightly taught without engaging the spring
• For the Short Box series you may need to place the box further away from the footbar. Be careful to ensure that it is secure

Get To Know Your Reformer Springs!

Getting to know how your Reformer springs work—and adjusting them to suit your body—can make a big difference in how effective and safe your workouts are. Be sure to check your machine’s manual, and when in doubt, ask a certified Pilates teacher to help you find the best setup for your needs.

    Hi!
    The foot strap on a Gratz does allow your foot to touch the frame of the Reformer but you’re actually not supposed to do that — the goal is to never have the strap loose and instead your legs are engaged and pulling the strap taught.

    To answer your thought about how the injured area gets strong again — In the classical system, the way you deal with injuries is to give a strong workout that avoids disturbing the injured area. So you modify or skip exercises that might bother an injured shoulder for example. After completing the main workout portion of the session, you then take the client to other apparatus in the studio to work on their individual needs. That would be the time to do exercises to help restore strength after an injury, for a shoulder injury the Arm Chair would be a great place to do the exercises you mentioned since the springs are very light and it was designed for this purpose.

    Here’s a few workouts that show the classical system in action. The one with Anthony Rabara teaching has a client whose shoulder bothers him at times so you can see how he modifies during the Reformer portion of the workout.

      I agree! I once had a Reformer with colored springs and find it so much simpler to have them all the same color :).

      I am contemporary Polestar trained and find absolutely no issues with spring translation. A medium spring on Gratz is a medium plus a light or a pre loaded medium on a BB. If you know the exercises, it’s a dawdle. What wd be interesting to compare is 1. Rehab type work with light springs, say, side seated arm pull on the TT…the Gratz springs are so much heavier, that I find it tough to envision how someone with an injury cd work with such heavy springs (but that’s my Polestar trained brain, always looking for a positive, pain-free movement experience for someone). Additionally, I wd love to be the body and film a series on how the proportions of the classical equipment differ from the contemporary equipment, and how those differences make things like transitions on the Reformer almost impossible to do well on the contemporary equipment! Also useful to feel the drag on the eccentric phase on the Gratz…I believe most of the work feels more effortful on the Gratz vs BB. Just my thoughts atm. X

        Genevieve I love your thinking – comparing the dimensions of different equipment would be a fascinating exploration and I’ve wanted to make that happen for years. Maybe we’ll get to a studio soon that has some mixed brands of equipment and can make this happen–where do you live by the way ;)?
        I agree that the Gratz Reformer spring is definitely too heavy for any rehab work and in my opinion that’s because it wasn’t designed for rehab. What I learned to do in the classical system is to leave out any reformer exercises that would put the injured area at risk and take the student elsewhere in the studio after the reformer portion of the workout to address the injury. For example for an injured shoulder the student would do seated arm work on an Arm Chair which has the lightest spring in the system. That said, I also get how contemporary Reformers are useful in a rehab setting where a PT is using them and approaching the work from a different perspective.

          Aha! So that’s the workaround…to move to a different area. How does the I hired area ever learn to move again?

          It was Sonjé Mayo whose classes I started doing live in March who told me that the proportions on my contemporary stuff are all wrong. There is no chance to say, teaser up, spin around 90deg and reach down to deal with springs on the long box that is part of BB reformers unless you have very gangly long arms. A relief to hear bc I have been saying to myself why the **** can’t I do this? Also swan on the long box as classically taught feels awkward on the contemporary equip…I am forever futzing trying to get comfy, as the box is higher and the edge on my model not as rounded. My other bug bear is that when I see how you can put yr feet in safety strap on the Gratz…it looks like yr feet have somewhere to go and can touch a surface on the bottom of the feet? On my BB Allegro, the safety strap setup means I cannot straighten my legs in short box unless I am happy to have my feet literally hanging in that strap with the bottoms touching…nothing. I am not sure about BASI or STOTT stuff. I live in the UK, halfway between London and Cambridge, btw. I think Alexandra Bohlinger is in London?

        Excellent observation; BB reformesr or color springs ones do have their place in re-habilitacion and comtemporary Pilates, as well as, easy movement for franchises Pilates like for example Club Pilates,. but in my opinion a Gratz or even Balance Body contrology model are my prefer choice to own an to teach.
        I will love to see a class in Pilatesology in contemporary Pilates moves to cover more need gap in todays instan gratification fast peace wold thanks for your opinion.
