My boyfriend, Stew, and I went to an indoor rock climbing gym this weekend, to do something different. I've done it a couple of times and absolutely love it! When you climb the walls, you have your harness, rope, and somebody to belay you during your climb. There are rocks that along the wall where you must step and grab onto in order to climb. Some rocks are easy to grip and others require more strength in your divi flexors (Finger flexing muscles).
What Is working?
Forearms - your wrist flexors play a big role in this activity for gripping and pulling yourself up.
Finger flexors- you have to grab and hold on to the rocks somehow. The flexor digitis, flexor pollicis brevis, etc., do a lot of work during your climb as you grab and hold onto the rocks.
Biceps- these arm muscles are engaged when your elbow is flexed. In order to pull yourself up, you need to have flexion in your elbow.
Quadriceps- as your legs push your body up to the top on the wall, you have to extend your legs. When doing this, the quads are activated.
Calfs- your soleus and gastrocnemius are the muscles involved in toe raise exercises. While rock climbing, you tend to stand on the rocks with your toes in order to help lift yourself to the next level.
Core- your back is also engaged in this activity. In your upper back you are using your Latissimus Dorsi, Trapezius, and Rhomboids. As you pull your arms from above your head to below your shoulders to help guide your body upward these muscles are engaged.
Your abdominal muscles act as stabilizers during the climb.
