The trunk, which includes the back and abdominal muscles, is a weak link for most cyclists. How many times have you heard of elite riders having to pull out of competition because of back problems? Why? Because they don’t have the torso support to resist the tremendous forces which their powerful leg muscles can generate.

Any force directed into the pedals also goes up into the torso. If the trunk is weak, that force DOESN'T go into the pedals but is dissipated in the flexing of the torso. Look at tired riders. Every stroke generates an "S" curve in the back, and it's this constant effect of the power of the legs that causes fatigue, and eventually, overwork and spasm of low back muscles.

In fact, a rider will never get stronger by pushing pedals as long as his torso absorbs the forces he creates, because he is negating the resistance of the pedals. Most riders give away significant pedal power because they do not possess adequate torso strength.

Back muscles are not adequate in themselves to supply the needed torso rigidity. Evolution has left us with musculature designed for quadripedal animals, and the muscles which could support a hanging, horizontal spine don’t stabilize a vertical one subjected to all the impacts and forces that upright posture dictates.

However, we have abdominal musculature which can aid in torso support. These are the muscles which contract the body to enable a running animal to bring its legs forward. The quads straighten the leg. The hamstrings bend it at the knee. The abdominal and groin muscles pull the leg over the top of the pedal stroke. But they do something else, too. They provide stiffness to the torso to support and reflect the force of the legs, whether pushing away against the ground in running, or pushing against the pedals in riding a bicycle. This is where we get stability on the bike.

If your only strength work is on your abdominals, this alone will vastly improve your riding. Strong abdominals are also the key to preserving a healthy back, and are the foundation of strength for a strong rider. Riding with undeveloped abdominals is something like riding a bike with a cracked frame. All the energy gets dissipated in flexion, and doesn't get you down the road.

Squats (with weight) are also a good exercise to strengthen the torso, if done right. The weight and torso should rise together as the legs straighten, with the abdominals tight, helping the back muscles to hold the torso rigid. If you can't lift with this style, you are lifting too heavy a weight.

So after you get off the bike at the gym during this winter season, stop by the weight room for a set of squats.

Speaking of core strength, here's some simple core exercises from GCN:



On the subject of planks, I just saw this post on tips for effective planking on Bicycling Mag. Interesting

"If done correctly, the plank can be the least complicated part of your off-bike routine—but it will have huge effects on your power and comfort in the saddle. When you really think about it, it’s kind of amazing how not moving while supported by your forearms and toes requires so much muscle coordination. In a proper plank, as Bruce Kelly, C.S.C.S., owner of Fitness Together in Media, Pennsylvania, points out, "The entire trunk should be engaged, from kneecaps to shoulders and literally everything in between: the lats, pecs, abs, obliques, glutes, and quads." To make sure you’re doing it right, take a cue from Kelly's good-form arsenal."

Key points:

* Plant your elbows directly under your shoulders at a 90 degree angle
* Tense up your midsection like you're about to take a hit
* Clench your butt
* Slow, controlled deep breathing
