What You'll Learn
Quadriceps, hamstrings, glutes, and calves are activated
Climbing stairs is a fundamental movement that requires the use of various muscles in the body. Quadriceps, hamstrings, glutes, and calves are activated and work together to propel the body upwards, providing stability and balance.
The quadriceps, located at the front of the thigh, play a crucial role in climbing stairs. As you lift your body onto each step, the quadriceps contract and extend the knee, providing forward and upward momentum. The deeper knee bend required for taller stairs increases the involvement of the quadriceps, which can often lead to a burning sensation in these muscles during a strenuous climb.
Hamstrings, located at the back of the thigh, are another key muscle group activated during stair climbing. They control the extension of the leg at the knee, working in tandem with the quadriceps to provide stability and control during the ascent and descent.
The gluteal muscles, including the gluteus maximus and gluteus medius, are also engaged during stair climbing. The gluteus maximus contracts to help raise the body onto the next step, while the gluteus medius prevents the body from falling to the side, providing essential lateral stability.
Lastly, the calf muscles, including the soleus, gastrocnemius, and tibialis posterior, are activated during stair climbing. These muscles are responsible for extending the ankle (plantarflexion) and keeping the ankle braced, providing a strong push-off from the balls of the feet. The involvement of the calf muscles depends on the technique used, with a higher degree of activation when pushing off from the balls of the feet compared to a flat-footed technique.
Overall, climbing stairs is an excellent way to strengthen and tone the lower body, engaging multiple muscle groups in a functional and challenging movement pattern.

Knee extension is required
The quadriceps help to stabilize the knee joint and take some of the load off of your knees when climbing stairs. As you climb stairs, you must swing your leg from an extended position into a flexed position in preparation for another stride. This is the job of your iliopsoas muscles, which include the iliacus, psoas major, and psoas minor. These muscles are located on the front of your hip.
The hamstrings also play a role in knee extension during stair climbing. They control the extension of the leg at the knee during the middle of the swinging phase. In addition, the gastrocnemius and tibialis posterior muscles are involved in plantarflexion, or ankle extension, which helps to keep your ankle braced and provides a strong push-off from the balls of your feet during stair climbing.
Overall, climbing stairs is a great way to strengthen your knee extensors and improve your lower body strength. It is a weight-bearing exercise that can help build bone strength and tone your legs.

Tibialis anterior and posterior are involved
Climbing stairs is a fundamental daily activity that activates the core muscles in your legs. The body uses various muscles to climb stairs, including the soleus, quadriceps femoris, hamstrings, and gluteus maximus.
The tibialis anterior and posterior muscles are also involved in climbing stairs. The tibialis anterior is situated on the lateral side of the tibia, and its tendon inserts on the medial border of the foot. This muscle is the primary dorsiflexor and inverter of the ankle and foot, contributing to maintaining the medial arch of the foot. During stair ascent, the tibialis anterior dorsiflexes the foot during the swinging phase, helping the limb to clear the step on which the supporting limb is placed. It also inverts the foot at the beginning of the supporting phase as the toe is placed on the lower step.
The tibialis posterior muscle is located in the deep posterior compartment of the leg and is responsible for supporting the medial arch of the foot and plantar flexion of the ankle. While the tibialis anterior is more commonly associated with anterior tibial stress syndrome (ATSS), the tibialis posterior is more involved in medial tibial stress syndrome (MTSS).
A study examining the electromyographic (EMG) activity of the tibialis anterior and soleus muscles during stair ascent and descent found that the soleus muscle had significantly higher activity than the tibialis anterior. However, the height of the stairs did not significantly affect the muscular activity of either muscle.

Erector spinae contracts twice per step
Climbing stairs is a fundamental activity that offers numerous health benefits, from improving cardiovascular health to strengthening and toning muscles. The erector spinae muscles, in particular, play a crucial role in maintaining stability during stair climbing.
The erector spinae is a large and superficial muscle that lies just deep to the thoracolumbar fascia. It is composed of three muscles, with fibres running vertically through the lumbar, thoracic, and cervical regions. The erector spinae is a core and paraspinal muscle, and its main function is to provide spinal support.
When climbing stairs, the erector spinae contracts twice per step to prevent forward bending of the trunk at the vertebral column. This contraction helps to maintain spinal stability and ensures efficient movement. The erector spinae works in conjunction with other muscles, such as the multifidus, to provide spinal support and improve posture.
By regularly engaging in stair climbing, individuals can strengthen their erector spinae and multifidus muscles, which can lead to improved posture and a reduced risk of lower back pain. Additionally, the contraction of the erector spinae during stair climbing contributes to overall core stability and balance.
Overall, the erector spinae contracting twice per step during stair climbing is essential for maintaining spinal stability, improving posture, and enhancing core stability. This unique muscle activation highlights the benefits of stair climbing as a comprehensive workout that targets multiple muscle groups simultaneously.

Iliacus, psoas major, and minor work together
Climbing stairs is a great form of exercise that can burn more calories than running, swimming, cycling, or walking. It is a vigorous activity that engages the body's largest muscle groups to lift the body weight repeatedly. Stair climbing targets the same muscles as squats and lunges, strengthening the lower body and toning the butt, thighs, calves, and hips. It is also beneficial for the lungs and cardiovascular system, improving endurance and reducing the risk of heart disease and stroke.
The iliopsoas muscle group, comprising the iliacus, psoas major, and psoas minor muscles, plays a crucial role in climbing stairs and various other daily activities. This complex muscle system functions as a unit, with the psoas major and iliacus often considered a functional unit, collectively known as the 'iliopsoas'. The iliopsoas muscle group is part of the inner muscles of the hip and forms the posterior abdominal wall. The psoas minor muscle is located in front of the psoas major, originating from the last thoracic vertebra and the first lumbar vertebra. It converges with the iliac fascia and the psoas major tendon to insert onto the iliopectineal eminence.
The iliopsoas muscle group is essential for maintaining correct lumbar posture during standing or sitting and stabilizing the coxofemoral joint. It helps move the hips, upper legs, and lower back, and supports the body during walking and running. The psoas muscles are core muscles that provide stability and facilitate movement. They start in the lower back, just below the ribs, and run alongside the spine through the pelvis, ending near the hips at the top of the femur.
The iliopsoas muscle group works in conjunction with other muscles during stair climbing. The raising of the body onto the next stair involves the contraction of the soleus, quadriceps femoris, hamstrings, and gluteus maximus, while the gluteus medius prevents the body from falling to the unsupported side. The tibialis anterior assists in the swinging phase of the gait cycle, ensuring smooth foot placement on the stairs.
In summary, the iliacus, psoas major, and psoas minor muscles are integral components of the iliopsoas muscle group, which is crucial for maintaining posture, stabilizing joints, and facilitating movement during activities like stair climbing. Their coordinated contraction with other muscle groups enables efficient locomotion and supports the body's weight during dynamic activities.
