I am 6'2 and weigh 67 kg.I am currently working out a muscle per day ,for six days.I do five exercises for each muscle . Is this ideal for gaining muscle mass?
Given your description of yourself, height, bodyweight, and the fact you are a beginner, you should be using a beginner routine. The truth of the matter is that the one muscle group per workout is an advanced body builder split. There really needs to be a foundation of muscle for that to work.
Training for Beginners
Jim Stoppani has a good approach to building mass taking you from beginner to advanced in 12 weeks. It boasts some features that you should pay attention to:
The breakdown is like this:
Now, Jim Stoppani's program isn't the only way to gain mass, but it addresses the needs of a beginner body builder and adapts as they grow. The truth is you won't be able to keep up with Phase 1 while you are using the weights you use in Phase 4. This is due to recovery needs. Your body needs to be able to rebuild itself into a stronger and bigger you after the stress of training.
The other side of the coin is food
The point of bodybuilding is to get bigger muscles, but stay lean enough that you can see them. You need to eat like a bodybuilder to see the improvements you want. It requires calories to build muscle, but you don't want to just blindly eat everything in sight. Another bodybuilding article on a mass building diet outlines what your diet should consist of:
You'll find that supplements on a mass gaining diet may not really be necessary, other than multivitamins and omega-3s. You will do better eating your carbs from rice and potatoes than you will from a tub of mass gainer.
If you have a hard time gaining mass, Jordan Syatt had a good article covering the typical issues "hard gainers" have:
You don't have muscles in first place,let alone working them separately,looking at your height and weight it seems that you are underweight.
I'll suggest you that you should eat big and perform compound lifts like Squats, Dead-lift, Bench Press, Overhead press etc. and you'll gain in size.No exercise is going to work for you if you are not eating enough. Don't worry about gaining some fat in the process,once you gain some muscle mass its easy to cut fat later,its very hard to gain muscle without fat.
Grab some beginner program like Starting Strength or Stronglifts 5X5 and follow it blindly without modification,It'll do wonders for you.
just Remember to Eat Big And Lift Heavy
