Top 10 Mistakes With Indoor Cycling Technique

I came across an article in the L.A. Times recently that covered a cycling studio that uses weights while on the Indoor bike. I began to wonder how far we will go with indoor cycling to make it so different and unique that it suddenly becomes unsafe and dangerous. Indoor cycling is an amazing cardiovascular workout and is extremely popular among all fitness classes offered around the world. However, as with all group fitness classes, there is concern that instructors try new and ‘exciting’ ways to do certain exercises on the indoor bike and some of these moves can cause injury. Along with Jillian Michael’s on The Biggest Loser as well as doing certain cycling techniques more often than not less is more when it comes to new ways to try and re-invent certain indoor cycling techniques. Many instructors use moves that may be dangerous in the name of creativity. Indoor cycling can be very safe, but make sure you are aware of the following top 10 mistakes that instructors make while teaching class or while using your indoor bike at home. Overall when it comes to designing and planning an indoor cycling workout: Less Is More! Focus on the beats of the music and try to keep it a simple cycling routine so that everyone in class can follow no matter what level you are. 🙂 Check out our classes at Roworx for more information about cycling classes!

Proper Indoor And Outdoor Cycling Technique And Form On The Bike

Over the past 10 years while teaching over 5,000 hours of indoor cycling classes throughout various fitness facilities across the U.S. I have found that in order to get the best workout on a bike you must have the right technique whether you are cycling indoors and or outdoors. Cross-training on the indoor bike has had added many positive effects to my training for two international Ironman’s in Nice, France and Florianopolis, Brazil over the past couple of years. I owe it to cycling for getting my body into the best shape of my life and improving muscle endurance throughout my legs and core. My father, John Nunn also used cycling as a perfect way to crosstrain for the Olympics in 1968 while winning a bronze medal in rowing. John also discusses the importance that indoor cycling bikes that offer the perfect cross training exercises with all the training benefits of road cycling and without the risks of crash injuries. The indoor cycling ‘boom’ hit in the late 1980’s and early 90’s with the emergeance of the ‘spin class.’ Since then almost every single fitness machine manufacturer has developed am indoor bicycle. Indoor and outdoor cycling have become so popular because nearly everyone knows how to ride a bike and the leg drive on a bicycle is a relatively simple process. You may either pedal with greater force, more pedal velocity along with resistance in gears or brake, or both to achieve greater speed and power. In order to accomplish this you must first transfer your body’s energy to the pedals. How much of this energy you transfer is determined by your efficiency and technique during the pedal stroke. There are many ways to increase power and efficiency. It is possible to be a fit and powerful athlete, but not necessarily a fast one if you are inefficient.

How Bike ‘Sway’ Contributes To Enhanced Leg And Core Strength While Sitting And Standing

The EVO Indoor Cycling Bike is very unique from the rest of the indoor bikes on the market in that it engages the whole body while cycling in and out of the seat while riding just as a real outdoor bike experience would be on the open road. Some cyclists would say that the less sway the better, however, the act of throwing every ounce of leverage, weight, and power into the pedals and movement side to side is the visible result of trying that hard to move forward when riding outdoors. If you could stay absolutely still, and input the same amount of force to the pedal, then more of that energy would go to moving forward, but it’s physiologically it is very difficult. It’s a matter of balance and leverage. Further, there is a mechanical advantage to be had in terms of body mechanics by swaying the bike and it lets the cyclist apply a bit more force than if the bike remained straight. The swaying motion from side to side will allow the cyclist to use more of his arm strength than would otherwise be the case. Being able to use your full body weight in a sprint has its advantages, and that’s one reason they shift the bike back and forth under them to ‘throw’ their body weight down on alternate legs side to side creates momentum and speed. They quite simply must sway the bike back and forth because of the mechanical reality of the situation. It’s not even really a conscious act and if a rider didn’t do this, the bike would fall out from under them. Sometimes you will actually see someone move a traditional indoor cycling bike off the ground from side to side and hop around the floor in class. These riders are applying extreme power to each pedal. Since the pedals are not centered laterally, applying a large force to the right pedal for instance will  apply a rotational force that pushes the top of the bike to the right and the bottom of the bike to the left. Without this counterbalancing motion, they would quite literally kick the wheel to the side out from under them. By ‘swaying’ the bike in the opposite direction, they increase the amount of force on the legs and core that can be applied to the pedals without crashing. It is an intuitive motion that happens completely automatically to any rider from novice to advanced. For a quick mental picture, imagine somebody swaying in the same direction as the pedal being pushed. For instance, somebody leaning the bike to the right while they apply a large force to the right pedal. The rotational force would rotate the bicycle clockwise, lifting the wheel off the ground. Not something you want to happen, especially at sprinting speeds and especially in a classroom setting. For a great example how this technique comes into play in real road cycling watch any Tour De France finish line approach. It’s incredibly intense and you can see how hard everyone sprints and works the whole body in order to get through the finish first. Legs, lungs, muscle endurance, and core play a massive role in the use of the Evo Bike!

10 Reasons Why You Should Use Indoor Cycling

Indoor cycling classes are an ideal place to work on the proper cycling technique and provide a traffic-free environment that can go a long way toward replacing the on-the-road experience. It’s a great place for cycling novices to improve at least ten aspects of cycling that will quickly make them a better rider. Indoor cycling is also a great place for the veteran cyclists to refresh their technique as long as they remember not to ride an indoor bike the same way they do their outdoor bikes. Whether you are training for an Ironman competition or just trying to stay in great shape be sure to incorporate indoor cycling into your weekly workout routine in order to improve muscle endurance and cardiovascular health. Tons of calories can be burned in just one cycling class and the best part is you can do it anytime anywhere.

How To Stay Motivated Throughout Your Workouts And Life

I Was Heading To The Gym But…

Even fitness buffs can have an off day. Here’s how to stay motivated, no matter what life throws at you.

There are many things that come up during the day that can distract you from your workout. You’re too tired, too hungry, too stressed, or just don’t have the time. Maybe you’re bored with your workout or progressing too slowly. Your favorite class is too overflowing with people or your favorite fitness machine is down for repairs. Your injured or sick in one way or another.

If you would have asked me 10 years ago that he was going to operate and own a fitness center in Long Beach I would have said ‘that’s crazy.. no way.’ I was always motivated through sports in one way or another and I loved the variety in which I could participate in most any sport. At one time in high school I was playing club soccer, Ice hockey, and rowing all in the same year. I had always dreamed about being paid to work out and compensated in one form or another. I graduated from UC Berkeley with a Communications major and minor in business hoping that I would write in a magazine or newspaper for a sports page. Funny how things turn out 🙂 When I moved home from the U.S. National Rowing Team In 2005 I was ‘burned out’ of the same fitness routine I had been doing for the last 15 plus years in rowing. I started teaching indoor cycling classes in order to change my routine and get myself back to a fitness regiment in order to be honest with my workouts. I had always trained on my own but I found that when training with a group there was an amazing feeling of high energy and consistency while exercising. Not only does it keep you honest with your workout but the sense of the group workout adds an effective high energy fat burning workout you won’t find anywhere else!
