Most individuals assume that the calf comprises one muscle however the truth is there are two muscular tissues within the calf. Probably the most distinguished leg muscle, which can be a lot bigger, is named the gastrocnemius.
It originates behind the knee, coming from both facet of the higher leg bone – the femur. It crosses the knee and ankle and connects to the heel bone – referred to as the calcaneus. Gastrocnemius helps flex the knee with the hamstrings and is essential to propulsion throughout strolling, working, and leaping as a result of it extends the forefoot down and the heel up.
The usually forgotten calf muscle is named the soleus.
The soleus arises from two bony factors:
Leg bone – referred to as the tibia.
The opposite bone is within the decrease leg, which is named the fibula.
Just like the Gastrocnemius, it will definitely connects to the heel bone – the calcaneus. The calf muscular tissues be a part of collectively into the Achilles tendon, which in the end connects them to the heel bone.
The primary capabilities of soleus
It really works with Gastrocnemius to assist push off with the forefoot however is extra energetic when the knee is bent as a result of it doesn’t cross the knee as Gastrocnemius does.
One other main position is to soak up pressure and stop the physique from falling ahead when stopping or decelerating equivalent to whenever you cease immediately whereas working ahead.
The Soleus has a really excessive proportion of slow-twitch muscle fibers as a result of it have to be energetic in all standing and strolling actions. This characteristic can be utilized to considerably improve calorie burning whereas sitting!
Skeletal muscle pump – The soleus acts as the first skeletal muscle pump that pushes blood from the decrease leg and toes to the center! It’s also known as the “second coronary heart” because of this.
Soleus push-ups for max calorie burning
In current analysis carried out on the College of Houston – scientists designed a particular seated soleus train that concerned offering contributors with visible biofeedback so they may study to repeatedly activate the soleus in a sure method.
The outcomes have been wonderful. Contributors considerably elevated their calorie burn with out feeling additional drained or confused! Contributors diminished their blood glucose by 50%. Once they examined the forms of gas used, they found that Soleus push-ups used gas from the blood, not like most muscle contractions, which use gas saved within the muscular tissues.
Contributors burned roughly 100 energy per hour for a number of hours with out feeling drained. The trick is that these seated heel raises have to be accomplished repeatedly and at a particular rhythm so as to reap these advantages.

The right way to strengthen the only real
The primary train to strengthen the soleus is leg raises whereas sitting. Many gyms have a leg increase board, however you may also use dumbbells or barbells in your thigh together with your knee bent at 90 levels, urgent down and elevating your heel.
It's additionally finest to raise the entrance of your foot so your heel can transfer by a variety of movement when doing seated calf raises. Since soleus is a fast-twitch muscle fiber, larger repetition plans are finest – 15 to 30 repetitions is nice.
