so everyone loves the basic 'bro split' and its been done for decades.
heres what a basic bro split looks like
workout 1 - chest
workout 2 - arms
workout 3 - legs
workout 4 - shoulders
workout 5 - back
repeat
the problem with bro splits is that most average people respond better to higher frequency, ie., doing a body part more then just once per week. mainly because they don't need a whole week to recover a muscle group.
now some genetic freaks that are naturally very strong (like most your pro bodybuilders) do just fine with bro splits.. thats because they generate so much homeostatic stress on chest day, because they are benching 500 pounds and dumbbell inclining 160 dumbbells, that they actually may need an entire week of recovery before hitting chest again . but mot of us are not here.
so I've taken the basis of the bro split and modified it for higher frequency.. your going to use the same bro split as listed above but simply add your frequency exercises in and hit the muscle group you just hit 2 days later on the second half of the main exercise..
heres what I mean
workout 1 - chest (but your going to do chest again 2 days later on workout 3 )
workout 2 - arms (but your doing to do arms again 2 days later on workout 4)
etc. etc...
so this is how it actually looks on paper
Workout 1 - Chest -- shoulders
workout 2 - Arms -- back
workout 3 - Legs -- chest
workout 4 - Shoulders -- arms
workout 5 - Back -- legs
now your first body part of the day is always going to be your heavier compound lifts .. your second body part you train on that same day is going to be your lighter weight isolation work .
so on workout 1 , chest day is the main day . you'll do mainly heavy presses and compound movements .. then that same day when hitting some shoulders you do light weight isolation.
so that day may start with bench press, machine press, dumbbell incline press , and end with side lateral raises, front raises and upright rows.
BUT when you hit chest again 2 days later on your leg day,, those chest movements will all be your lighter weight isolation moves , like pec dec, cable flies, etc.
so in this program your able to do the basics of a bro split, but still hit body parts at least 2x per week rather then once , but provide a good combo of compound and isolation exercises
