Cycling's Muscle-Building Power: Which Muscles Are Targeted?

what muscles are built cycling

Cycling is a great way to build muscle and improve fitness. While it is predominantly an endurance activity, cycling also builds muscle in the legs, hips, bottom, and feet. The quadriceps, hamstrings, and glutes are the primary muscles used in cycling, with the gluteus maximus being the largest and most powerful muscle in the group. The calves, abdominals, and erector spinae are also engaged for stability, and the adductor magnus (groin muscle), soleus (calf muscle), and hip extensors are also activated. The upper body and torso are not neglected either, with the arms, shoulders, and core also getting a workout, especially when mountain biking.

Quadriceps

The quadriceps muscles are the primary movers when pushing through the pedal stroke, so stronger quads equal more power. The quads and glutes supply two-thirds of the power we push through the pedals. The quads are responsible for pushing down on the pedals, which generates the most power in the pedal stroke.

To build leg muscle on a stationary bike, you have to pedal with a lot of resistance. Some indoor cycling programs recommend a resistance where you can't move the pedals faster than 60 revolutions per minute, or at an intensity you can't maintain for more than a minute or two to stimulate the greatest quadriceps-building effects.

To build quad strength, you can also try "hovers", which involve pedaling in a seated position while holding your bottom about an inch above the seat. Another quad-building exercise is to ride on a flat stretch of road in a big gear that slows you down to walking pace. Stay in the saddle and forcefully push the pedals, increasing your pace until you reach top speed. Hold there for 30 seconds, then shift back down and spin easily to recover for a minute. Repeat this process 5 to 8 times, and perform this exercise once or twice a week.

It's important to stretch the quadriceps before and after cycling. A simple stretch is to pull your heel towards your buttocks while standing.

Hamstrings

Cycling is an excellent way to build endurance and improve cardiovascular health. While it is a great workout for the legs, it does not work all the muscles in the leg evenly. The hamstrings are one of the muscle groups that cycling works out, but not completely. The hamstrings are a part of the upper leg, along with the quadriceps, and they play a supporting role to the prime movers.

The hamstrings are important in cycling, but they don't do as much work as the quadriceps unless you are pulling harder on your upstroke than pushing on your downstroke. This pulling action is called a "scrape" and can increase your power output. The hamstrings also contribute to hip extension, which is a primary movement of a pedal stroke.

Cyclists often have weak hamstrings in comparison to their quadriceps, which can lead to muscle imbalances and injuries. This imbalance can manifest as knees sticking out to either side while pedalling. Therefore, it is important to strengthen the hamstrings independently to avoid these issues. Some exercises to strengthen the hamstrings include squats, box squats, and calf raises.

In addition to the hamstrings, cycling also works the calves, quadriceps, hip extensors, and adductor magnus. The calves and hamstrings play a supporting role to the prime movers, the glutes and quads, which supply two-thirds of the power we push through the pedals. The hip extensors are the most powerful muscle in the body, so it is important to recruit them efficiently by positioning yourself high and forward on the bike.

Glutes

Cycling is an excellent way to build and tone the glutes, which are some of the most important muscles in the body. The glutes, or gluteals, are composed of the gluteus maximus, gluteus medius, and gluteus minimus. They are responsible for hip extension (straightening the hips) and external hip rotation (rotating the thigh outwards). The glutes also function to produce power from the hips in athletic movements such as cycling and jumping, and to stabilize the knee by controlling movement in the thigh bone.

When cycling, the glutes are engaged throughout the majority of each pedal stroke. If you think of the pedaling motion as a clockwise movement, the glutes are primarily activated between what would be 12 and 5 o'clock on a clock face. This is the 'push' phase, where the glutes and quads work together to straighten the knee joint.

To further engage the glutes while cycling, it is recommended to move forward in the saddle, similar to a triathlete's sitting position. This position increases the effort required from the glutes and reduces the burden on the quads. Pointing the toes towards the ground can also help to engage the glutes more during the pedal stroke.

Additionally, performing glute activation exercises before cycling can help to "wake up" the glutes and improve glute strength. These exercises involve contracting the glute muscle and include moves such as the glute bridge, where you thrust the hips to lift the glutes and lower back off the floor.

While cycling is an effective way to build the glutes, it may not lead to significant muscle growth, especially for those who are very skinny. This is because cycling is primarily an endurance sport, which favors smaller muscle mass. For those seeking to increase glute size and strength, incorporating strength training and power training exercises, such as squats and box jumps, can be beneficial.

Hip extensors

Cycling is a great way to build up the muscles in your legs and hips. The hip extensors are a group of muscles that include the gluteus maximus, the hamstrings (including the long head of the biceps femoris, the semitendinosus, and the semimembranosus), and the extensor head of the adductor magnus. These muscles are responsible for producing the greatest torque across the hip compared to other hip muscle groups.

When cycling, the hips are in a constant state of flexion, which can lead to tight hip flexors. The hip flexors are made up of the iliacus, psoas major, and rectus femoris, and they work together to produce hip flexion, or the movement of the knee towards the abdomen. Tight hip flexors can cause hip pain and affect your posture and comfort while cycling.

To improve hip flexion and reduce pain, cyclists can adjust their bike setup, ensuring that the hip is not forced beyond its available range of motion. This may involve moving the saddle forward and up to create a more open hip position. Additionally, moving the cleats to a wide and back position can give the hips more space.

To strengthen the hip extensors, exercises such as squats are beneficial as they replicate the power phase of pushing on the pedals and target the hamstrings, hips, and lower back. It is also important to focus on core strength, as it helps transfer force through the legs and improves stability.

Overall, by incorporating strength training and ensuring a proper bike setup, cyclists can improve their hip extensor strength and reduce the risk of hip pain and injury.

Calf muscles

Cycling is an excellent way to build calf muscles, but it is important to note that the intensity of the workout and proper form play a crucial role in achieving significant muscular gains. While cycling primarily works the muscles in the legs, such as the quadriceps, hamstrings, and glutes, the calf muscles are also engaged and can benefit from increased muscle mass and endurance.

The calves, along with the hamstrings, play a supporting role in cycling. As cyclists push against the resistance of the pedal, especially when climbing hills or sprinting, the calf muscles are continuously activated. This activation builds muscle mass and enhances muscular endurance, making it easier to perform long-distance cycling where stamina is crucial.

To maximize the benefits of cycling for calf development, it is essential to incorporate varied cycling routines and ensure a proper bike setup and posture. Including hill climbs and sprint intervals in your routine can significantly enhance calf muscle growth and strength. The high-intensity nature of these activities demands explosive power from the calf muscles, leading to substantial muscular gains.

However, it is important to note that the muscle groups in the calves, ankles, and feet might not contribute as much to power generation as other muscle groups. Additionally, the development of calf muscles through cycling can be influenced by factors such as genetics and body fat percentage.

To further strengthen the calf muscles, it is recommended to incorporate specific strength training exercises such as deadlifts, calf raises, and squats (rising onto the toes). Regular jumping and skipping rope can also help improve calf muscle strength and endurance.

Frequently asked questions

Cycling is an endurance activity that builds the muscles in the hips and legs, including the glutes, hamstrings, calves, and quadriceps. The upper body muscles are also engaged, especially when mountain biking, and are used for balance and stability.

Exercises that focus on the hips and legs, such as squats and Romanian deadlifts, can help build strength for cycling. It is also important to train the core muscles for stability and balance.

Cycling is primarily an endurance activity that works the slow-twitch muscle fibres, while strength training focuses on building power and targets the fast-twitch muscle fibres. Cycling can help build muscular endurance, but it is not a replacement for strength training.
