…you’d be suprised how little you have to do to get big results.

my personal workout splits is 5 days monday – friday, cardio on saturdays and sundays.

monday – chest (3×8 weighted dips with 45 lb plate, 3×8 bench press, 3×8 incline dumbbell press, 3×8 flat bench dumbbell flies.)

tuesday – back (3 sets of pullups until failure, 3×10 dumbbell rows, 3×8 barbell rows, 3×10 lat pulldown machine, 4×12,10,8,6 deadlifts)

wednesday – shoulders/traps (4×12,10,8,8 dumbbell military press, 3×8 barbell press, 3×10 lateral raises, 3×12 dumbbell shrugs)

thursday – legs (4×12,10,8,6 squats, 3×10 lunges, 3×10 calf raises and some leg machines)

friday – arms triceps/biceps some forearms (SUPERSET meaning doing a set of biceps right after triceps) (3 sets until failure weighted dips superset with 3 sets until failure weighted CHINups, 3×8 skull crushers superset with 3×8 close grip barbell curl, 3×8 close grip bench press superset with 3×8 hammer curls).

that’s my current split, i change it up every 3-4 weeks. not telling you that this is the workout you should do, but it has added on about 5-6 pounds of solid muscle mass on my body.

try to avoid doing chest and shoulders together and arms the next day. chest and shoulders both work your triceps and doing triceps the next day is overkill. gotta rest them first.

just remember that gaining muscle mass is 1/3 working out, 1/3 sleeping, 1/3 eating.

working out triggers the growth, sleeping gives the the rest and time to rebuild and grow bigger, eating fuels the growth. you may be an animal in the gym but sleeping 4 hours per night and undereating calories will not give you good results.
