Re: I cannot even do 1 pull up. What muscles should I train to improve this?
Proper pull ups use a lot of the upper back muscles.
So do some rows and lateral pull downs.
Pullovers are chest dips are good compounds.
Also, belly fats are solved by proper diet, good rest intervals and exercise.
Exercise will only bulk up your ab muscles, it won't remove the fat on top of the muscles unless you live a healthy lifestyle.
