Final answer:
The statement is false; calf raises target the gastrocnemius and soleus muscles in the lower leg, not the rhomboids. The gastrocnemius is the largest muscle in the lower leg exercised during a calf raise.
Step-by-step explanation:
The statement that a calf raise exercises primarily the rhomboids and soleus is false. Calf raises primarily target the muscles in the lower leg, specifically the gastrocnemius and soleus muscles, which are connected to the calcaneus bone via the Achilles tendon. The rhomboids, however, are muscles of the upper back that are involved in retracting the scapula. When one performs a calf raise, they are primarily using the gastrocnemius and soleus muscles to pull on the Achilles tendon and lift the heel off the ground. Therefore, the largest muscle in the lower leg that is exercised during a calf raise is the gastrocnemius, not the rhomboids.
