Variable Resistance Strength Training for Climbing with Elastics

Lifting a weight (or lifting your body) normally does involve varying levels of force during exercise due to acceleration. If you recall from physics, force equals mass x acceleration. Gravity is 9.8 meters per second squared so that gravitational force is constant. However, when raising a weight (or your body) up and down, you are accelerating and decelerating the weight vertically, so the force is usually highest near the bottom as you reverse it and start accelerating upward. At the top of the range of motion, force is normally lowest, especially if you don’t pause there. If you perform an exercise more slowly, the acceleration varies less, i.e. the force remains more constant. That’s not necessarily good or bad, it just depends on the specificity compared to what you are training for. As a climber, it is helpful to be strong at the top of a lock off in order to reach a far away hold so it’s worth giving it some attention in your routine. This is one of several benefits from using elastics to modify the force curve of common strength training exercises.

Enter the elastic band: Elastics such as rubber tubing have nominal mass so exercising with them minimizes force from acceleration. The resistance (tension) is a direct result of changing length – i.e. the amount of stretch. At zero stretch, the force is zero. As length increases, the force increases more or less linearly until some extreme point at which it breaks and force becomes zero again! Fortunately the elastics made for exercise can withstand a lot of stretch before they break.

At some point some in history, strength trainers started combining the two to get the consistent force you get from lifting weights while taking advantage of elastic force to accentuate the resistance at the top of each repetition. A specific example is a powerlifter who fails to ‘lock-out’ their bench regularly – they want to train the top part specifically to address this weakness. Turns out it works pretty well and has now become fairly commonplace. Most stores selling strength training equipment now have these heavy duty elastics in addition to traditional rubber tubing used for rehabilitation.

Here’s a photo of a guy bench pressing with elastics which clearly demonstrates the concept.

I had been pondering this technique but hadn’t really made a serious effort to make it work. This last weekend I decided to finally give it a shot with my fingerboard training and was really please with the results! As a quick summary I would say the following are the main advantages:

  • For pull-ups, it felt very realistic in the sense that the effort was the highest near the top of the movement. Furthermore at the bottom, the resistance was the least, which helped alleviate some of the shoulder and elbow strain that can occur when fully extended.
  • For deadhangs, I was able to work on more difficult hangs than usual. I could do one-arm hangs from a medium size edge which I can normally only do on a large edge/pocket/jug. With two arm hangs I could safely hang 10 seconds on a small edge that I can normally only hang for 2-3 seconds with some discomfort.
  • The gear involved was fairly basic and inexpensive – in addition to a fingerboard I had a ring bolt below it, a loop of high tension rubber tubing, a climbing harness, some carabiners and slings, a 12 kg kettebell (ok, KB’s are a bit pricy) and a mat underneath to pad the floor.
  • The set up was much easier for each set than using pulleys  with weights, which can be finicky.

There are two general ways I tested, and both were very effective and fun!

Method 1: Assisted Deadhangs and Pull-ups

First, I used the loop of rubber tubing to assist by fixing one end right under the fingerboard and stretching the other end down under one or two feet.

This image shows how I set the loop length so that the assistance was equivalent to about 20 lbs pushing up on my foot (or feet).

As you can see the 25 lb dumbbell reached the floor, but the 15 lb dumbbell was suspended. I don’t have a 20 lb dumbbell but can safely infer that the tension was around that level.

In the next image you see the set-up where I pulled to elastic down to my right foot, then stood up straight, grabbed an edge with a bent elbow and then raised both feet of the ground, and hung for around 8 seconds until fatigue. I did a few reps of this on each side and it was effortful, but painless, and the hang durations were in the desired range.

I don’t have any photos here but I also did two arm hangs from the small crimp (open crimp actually, no thumb) and I could hang for a more useful duration (8-10 second) before fatigue/pain set in.

This method, I found was awesome for deadhangs, to work on more extreme grips (two hands) or one handed hangs on medium sized grips. Also it can be used for assisted pull-ups to provide some assistance at the bottom but much less at the top, for extra strength training stimulus at that range.

Method 2: Pull-ups with Additional (Variable) Resistance

The other way I tested was to hang a weight from my harness so that it rested on the floor when hanging with straight arms, but part way through the pull-up, the tension exceeded the weight (12kg) and it lifted up off the ground. From the following demonstration you can see how this works.

the following shows me doing a pull-up with this assembly clipped to my harness. I had to add a few carabiners to extend it and get the weight to lift up at the right time. This takes a bit of experimentation but one you get the length right, it is very easy to hook in and go. I did find that a kettlebell worked better than a dumbbell because its shape is more conducive to consistently landing upright. Also, its good to have a mat underneath so as to have a softer touchdown and not dent the floor.

This method was very good for pull-ups from medium sized grips because the extra effort at the top of the range was really noticeable, recruiting muscle fibres when you want them firing the most!


Overall I am very psyched on these two methods. I’m going to pick up some more heavy duty rubber bands from the fitness equipment store and try some more variations. But experimentation aside the workout was very good. It felt like it would result in good strength gains due to the new variation from the norm and added specificity of the pull-up force curve. Lastly I can easily think of ways to make the exercises incrementally harder so I can track my progress. It’s safe to say this method is here to stay, in my training routine!

If you are an experienced climber and trainer I recommend you give this a try and let me know via Twitter how it goes for you. Thanks for reading and happy training!

Squamish Boulder Co-operative

Having lived in Squamish (or Squampton as locals affectionately call it) for 2.5 years, I’m slightly embarrassed to admit that yesterday was the first time I’ve been to the Squamish Boulder Co-op. But, better late than never, right? A lot of my friends go there regularly because there is no commercial climbing gym here. “What” you say? How can that be? Well, Squamish has a population of around 17,000 people which is not very big. Also, there is a lot of climbing plus many other activities like mountain biking, trail running, hiking, kite boarding, skiing, snowboarding, etc. to be had outside. Finally, many hardcore climbers have their own climbing wall in their garages, cellars, etc. For me personally, most of my training is on my home wall which has served me very well.

How does it work if it’s not a commercial gym? Well, all members become shareholders for $5.00, then membership dues to use the gym are used to cover rent, heating and new holds. The facility has no staff so to my knowledge, and the labour is all done on a volunteer basis by the founders and members. Very groovy and utopian, right?

I went their finally as my good friend Jamie Finlayson had been urging me to go for quite some time. I was pleasantly surprised with the size of the facility and variety of holds and angles. Also, the are a lot of holds made from wood, as one of the founders has a woodworking shop and some pretty impressive skills (in woodworking and climbing). There is even a skateboard deck bolted to the wall! I’m a big fan of wood holds because they make you work much harder than most plastic resin holds, and don’t wear out your skin as much.

Jamie showed me some of the classic problems which are not marked with tape or anything, they are either logged in a binder at the front, or, in the memories of the members. I could do a few of them at least. We made up a few more together. Fortunately all my training on my home wall over the last few months has started to pay dividends!

After a few hours of bouldering we did some campusing – they have a very tall campus board, which I love! Then we did some gymnastic ring exercises, which are always a good way to finish a workout, strengthening the core and stabilizers.

Below are some photos of our gymnastic ring training with some great exercises for climbers!

Exercise of the day – The Horizontal Pull-up

The Horizontal Pull-up

This a exercise is great alternative or complement to the standard pull-up, which is arguably more sport-specific for most climbing situations, since we usually have our feet on the wall and are using our arms to pull our centre of gravity into the wall.

Here are some of the key features of the exercise.

  1. The main difference with this exercise if that your feet are positioned on the ground or a chair/stool so your body is somewhat horizontal. The higher your feet are, the more horizontal you will be, making the exercise harder.
  2. Usually the exercise is done on a bar if you are at a gym or outdoor playground, or gymnastic rings that can be lowered to approximately 4 feet or 1.2 meters off the ground. The latter is my preference but the bar option is more commonly available when travelling etc.
  3. It can be done with either two-arms, or if that is too easy, it can be done with a single arm.
  4. The motion should be completed at a ‘regular’ pace –  approximately 2 seconds on the way up, 1 second pause at the top, and 2 seconds on the way down. The lock-off at the top is important for climbing since we regularly have to do this when reaching up with the other hand.
  5. The number or repetitions obviously depends on your strength, body weight, whether you’re using two arms or one arm, and how elevated your feet are. The number or repetitions should be between 6 and 12 for strength and between 12 and 20 for strength-endurance. You can adjust these parameters to get to the right range of repetitions. (One more option is to use a weight vest if you have one and you’re super burly!)
