We all know the typical muscle gaining workouts: Monday-Back, Tuesday-Legs and the endless other 5 and 6 day splits.
What I'm willing to be that you don't know is that by doing splits like these, you are in fact hindering your progress.
Lifting weights more than 3-4 times a week will only cost your muscles extra time that could be recovering as well as extra calories they could be using to grow stronger.
You don't need to kill a muscle to make it bigger.
You just need to put it under progressively larger strains so that it adapts by becoming bigger and stronger.
The best muscle gaining workouts are one that comprise of various muscle groups over about 3 days.
Doing dead lifts and bench press in the same workout is just fine! They don't get bigger and stronger in the gym, they get that way when you're home sleeping.
So instead of doing your typical "arm" or "leg" day, try cutting your routine down to three days and mix everything up.
For instance, for good muscle gaining workouts, Day 1 could be: Squats and dead lifts, seated rows and incline bench presses, pull downs and shoulder presses, calf raises and shrugs.
By mixing up your routine and cutting down the amount of hours you actually spend in the gym, you give your muscles a real, fighting chance to actually become bigger and stronger.
The typical routines give typical results to most guys.
The only people getting really big off the typical splits are the one's with great genes who can afford to spend tons of money on supplements each month.
Stop using the typical muscle gaining workouts if you want to see results.
