Coaches: I need to build a new set of wall bars (or stall bars, depending I guess on what region you’re in?). I want to know if anyone has ever seen a style of wall bar that they think is both effective AND visually appealing (and accessible to all heights/ages of kids)? In other words, what’s the best design you’ve ever seen?

A couple of weeks ago, a reader asked me to drop some comments on bridges. It was asked something along the lines of why do coaches insist that gymnasts straighten their legs and keep their feet together when bridging?
I don’t know.
As I noted in my last post, repeated bouts of lumbar flexion are believed to be a potential risk factor lumbar spine disorders such as a herniated disk. Just the same, the lumbar spine really is not made to excessively arch or hyperextend as is seen when gymnasts perform skills such as bridges, backbends, and back walkovers. Aside from these skills, when does a gymnast actually assume this type of a position?
Quite honestly, I cannot think of any other skills in which a gymnast assumes this position with so much lumbar hyperextension. Some may argue that this type of bridge development is necessary for a successful performance of a back handspring. Or, that’s an argument that I’ve heard a few times over the years. Is it really? Below, are three screenshots taken from Shawn Johnson’s first tumbling pass at 2008 National Championships. Notice that she never gets into the position that we see above and if she did, she wouldn’t be very successful.
Does any gymnast ever assume the position (as shown in the bridge picture above) in a back handspring or any other skill except for bridges, back/front walkovers, etc. ? The important factor in bridge development is shoulder flexion or often – hyper-flexion. In other words, we want the arms to be able to be lifted up by the ears or even past without the chest/ribs poking out.
As I discussed in an earlier blog posting, there are other factors that we must consider when a gymnast has “tight shoulders.” Maybe the issue is not flexibility at all. Maybe the issue is too much rounding of the upper back that which places the scapula in a poor position. Maybe it’s a matter of poor scapular stabilization or an imbalance of the scapula musculature. The key muscles that would limit shoulder hyperflexion are the latissimus dorsi and the pec major/minor. There are other stretches specific to these muscles that do not stress the low back.
With that said, here is a better way to perform a bridge. I first came across this suggestion from David Adlard in an old USAIGC publication called STEPing UP. To minimize the excessive hyperextension of the low back, elevate the feet to above shoulder height and put the emphasis of the stretch on the shoulders.
In the picture below, a trainer colleague, Becky (who used to cheer and tumble in high school) demonstrates. Thanks Becky! She’s a little tight in the shoulders, but now this position can better emphasize the muscles that need to be stretched without putting the low back at as much risk. Afterwards, she even commented something to the effect of – “Wow, that really stretched my upper back…it felt good…”
Dr. Stu McGill from the University of Waterloo in Canada has strongly advocated that repeated lumbar spinal flexion (i.e. rounding of the low back) may ultimately lead to a disk injury. The question that remains unanswered is how many will it take to lead to injury? That’s probably a question that is HIGHLY variable depending upon the individual.
Nevertheless, I have pretty much stopped doing crunch/sit-up-type exercises. I feel that you can achieve the same effect performing core stabilization exercises such as planks. The closest that I come to a crunch is a reverse crunch, which I feel is a lead-up to performing a candlestick/lever raise on the floor, hanging on a bar, on the rings, etc.
With that said, here’s a study that was conducted on US Army recruits comparing a sit-up training program vs. a core stabilization program on performance of the US Army Physical Fitness Test. What was found was that –
“….there was a small but significantly greater increase in sit-up pass rate in the CSEP (5.6%) versus the TEP group (3.9%).”
CSEP = core stabilization exercise program
TEP = traditional exercise program

What are your thoughts?
Received an e-mail the other day requesting more information about proper landing mechanics. Here’s an excerpt from the e-mail:
Could you talk a little about landing positions, if you haven’t already done so? I remember reading a comment recently about coaches emphasizing legs together on landings, but it makes more kinesiological sense to have knees and feet shoulder width apart. The Gymnastic Minute on YouTube addressed the correct landing posture today, but I’d like to have a more in-depth explanation.
Here’s the YouTube video that this individual is referring to:
In terms of the feet being together versus apart, a wider base of support allows for more stability. Secondly, it is nearly impossible to get the hips shifted back enough to allow the glutes and hamstrings to assist in absorbing the energy from the landing if the feet are together. Why is this important?
The hamstrings originate on the ischium of the pelvis and attach on the back of the tibia (shin bone). Their main job is to bend the knee and their secondary job is to open or extend the hip. Well, as the knee bends from a landing, the hamstrings will activate and pull the shin bone backwards. This takes some of the stress off of the anterior cruciate ligament (ACL). The ACL attaches at the back of the femur (upper leg bone) and the front of the tibia. Its main job is to prevent the tibia from moving forward too much. So, if the hamstrings activate and pull the shin backwards, this takes some of the load off of the ACL.
Now for the glute max. The glute max’s main job is to open the hip (extension). However, the glute max also helps in controlling rotation of the femur since it partly inserts on the greater trochanter of the femur. (I say “partly” because part of it also forms with the TFL and creates a sheath that runs down the side of the leg known as the IT Band and this connects on the side of the tibia) Further, it assists the gluteus medius (as Kris Robinson mentions in the YouTube clip) in preventing the knees from dropping in – known as “valgus” position.
Controlling rotation of the femur and preventing it from dropping inward is very important to knee health. Coupled with an inwardly rotated tibia, you’ve got the makings for disaster. This is why what appears to be a perfect landing could end with the gymnast on the ground in agonizing pain. Having been witness to a couple of these in my coaching career, I now have a better understanding behind the “why.”
While this is all well and good, the problem is that gymnastics promotes a quad-dominant landing despite the obvious biomechanical problems that it presents. Despite the traditional gymnastics approach, I encourage all of you to think about the health of your gymnast and consider having them bend at their hips a bit more and push their butt backwards to allow for the glutes and hamstrings to engage more and assist in absorbing the landing. Your gymnast’s knees will be thankful later.
Anyway, I hope this offers some insight into proper landing mechanics and their importance.
Josh submitted this comment about basics and conditioning:
I love the philosophy and mindset that you have, I just wish that everyone thought the same way. I do have a couple questions though. I really like conditioning and love to do it at the end of class, however my classes are very short and there is not much time. What are some things that you can do during class to “make-up” for this? Another thing is how can you make the kids feel like they are not being punished? I try being upbeat about it, even join them every once in a while but they seem to still act like it’s because they have done something wrong. Thank you!
I empower my Cheerios to live in a state of constant fear by creating an environment of irrational random terror.
I have a pretty extensive video library of gymnastics training videos that I’ve either bought, recorded myself, or copied from other coaches. So, I pulled several excerpts from one of my favorite videos – “Double This, Double That.” This is a video that was distributed by the former USAIGC and is a lecture put on by Dave Adlard around 1996.
Dave and his wife also host a big meet out in Coeur d’ Alene, Idaho called the Great West Gym Fest.
This lecture is not only entertaining and informative, but it has been very instrumental in shaping a lot of my philosophy and ideology on gymnastics training. If you are still not convinced about the importance of sound basics in a developing gymnast, hopefully if we continue to “beat a dead horse into the ground,” we can convince you!
Maybe those of you who read this blog are convinced. Fantastic! Unfortunately, every time I walk into a meet, I constantly see the same stuff – sloppy, poor technique and it all stems from neglected basics. So, it’s pretty obvious to me that not everybody gets it. Oh, they all “talk the talk,” but I see so few who “walk the walk.”
Here are two excerpts from the video. The first video talks about training gymnasts right the first time and the second excerpt explains how practice is permanent.
Again, these excerpts were taken from a VHS video using Dazzle software. If the sound quality is poor, I apologize. You should be able to hear fine if you turn up your speakers or plug in your headphones.
