Arms (triceps and biceps)
This is actually the area I focus
the most, there's been an amazing improvement on my biceps, as well as my pectorals and i couldn't be any happier about it.
Focusing mainly on one muscle group when working out which is also know as isolation exercise may not really be good for it may not give you the required balance, sometimes it make us look shapeless and unbalanced on the ground.
You must missed the part I said
THE MOST I never said I neglect other areas or muscle groups that needs working on, I only said I focus more on my chest and biceps because those are the areas I feel needs more work than others, and those are also the areas that the push ups focuses more on.
I also engage on other home workout activities that focuses on building other areas of my body, like my legs, abs and other areas.
