Double Rainbow-from your exercise selection it sounds like you may not be working out at a gym, is that correct?
If so, you could buy a bar and some weights on craigslist for $50 and add deadlifts to your routine. That alone would add a lot of mass.
Here was my old college plan that helped me go from 130 to 170 in a year back in 1999. (Damn I miss college!)
Deadlifts 5 sets of 5
Chins 5 sets of 6
Seated cable rows -4 sets of 12
Incline Bar Bench 5 sets of 5
Close grip bench press 4 sets of 12
Dips 5 sets AMRAP
Squats 5 sets 10 reps
Leg curl 5 sets 6 reps
Also WHAT do you eat at mcdonalds? A happy meal? (10 grams of protein lol) 4 grilled chicken sandwiches throwing away 3 of the buns? (This is prob closer to what you should do)
Mcdonalds has a big menu...give us some details.
