I agree with YounusK and enrlevel's advice.
Cut down the number of exercises.
Focus on compound movements.
High reps (20 reps) with medium to heavy (if possible) weights (slow & steady) and last set with heavy weights that enables 3 reps at least, in perfect form.
Or stick with 3 sets of 10 reps. Cut break between sets to less than 10 seconds.
1 gram of protein for every pound of bodyweight.
Carbs: Stick with whole bread/roti. Total daily intake six slices of bread or two rotis. Majority of your food should include yogurt, milk, eggs (with the yolk), fruit, raw vegetables (that you can stomach) and good old animal protein.
If you're looking to gain mass drop cardio. By moving between exercises within ten seconds you would be getting quite a cardio 'Vascular' workout.
For biceps remember this principle, compound, stretch and contract. First one comes with barbells, second with isolation (incline dumbbell curls) and lastly preacher curls. Google Larry Scott.
The same principle can be applied to the triceps (seeing how they constitute 2/3 of the arm. It would be foolish not to take them into account), and other body parts, somewhat.
My exercises:
Clean & Press: favorite exercise for building functional strength.
Dead lifts: Overhand grip. (Alternate grip allows more weight to be lifted but in the long run it ruins your back. If you get over zealous)
Squats: Hack, box, front.
Forearm curls, Dave draper style.
Barbell curls
Incline dumbell curls
Triceps pulldowns
Standing skull crushers
Dumbbell swings, clean & presses
All of the above exercise are done on a 3.5 inch thick bar/dumbells.
(Where applicable)
The reason for listing these exercises is for you to know that it doesn't take a lot of exercises to build muscle mass or strength. But what it does take is a lot of respect for the other's advice, discipline and a work ethic that you've never experienced before. Since it is difficult to inculcate the last habit without a lot of pain and anguish, I would suggest you to join a proper gym which has if not professional then at least amateur bodybuilders working out. Or at least whose owner is a practitioner of the iron game. It would help you in avoiding a lot of back, knee, bicep, elbow and other muscle and joint related injuries. Good luck
Edit:
At a bodyweight of 78 kg;
I was deadlifting (regular sized Olympic bar), with an alternate grip 160 kg for singles.
Clean & pressing (same bar) 60 kg for singles
Box squats; (3.5 inch thick bar) 98 kg for singles.
I used the word 'was' because at the time I did not know about proper diet or nutrition. It was mostly carbohydrate based.
By the time I did get to know I had already incurred too many injuries and the doctor advised me to lay off weightlifting for a year. I couldn't lift for three. By the time I came back to it, I had lost all interest.
I lifted my old barbells yesterday and they brought back good memories. Saw your post, so thought I'd share a little experience.
