JKurz, i, just like debaser, am an adovcate of low volume and high intensity. Believe me i used to be doing exactly what you were, training 5-6 times a week, cardio once or twice a day, but after a while i got diminishing returns. I had heard about DC training and HST from someone at school. At first i was like "are you fucking serious?" one set for a bodypart how the fuck is that supposed to work. I started DC training, and BOOM gains like fucking crazy, and they havent really slowed down. The only downside of the program was i dont have a training partner, so i mostly do my work in the smith machine or hammer strength (except for squats and deads of course). But it didnt matter to me b/c my muscles KEPT getting bigger, and i was always adding weight or reps to the bar! Not only have i gotten much thicker and fuller, but i never get that overtrained feeling, and i am out of the gym in 50min tops.
Heres an example of one of my splits would be for a week:
warmup sets 2-3, none close to failure
Mondays:
Chest- smith machine inclines 1x10+3+2 RP
Shoulders- Smith Machine Military Presses- 1x8+3+2 RP
Triceps- reverse grip benches in smith machine- 1x10+3+2 RP
Extreme Stretches for all three
Back width- Pulldowns 1x8+3+2 RP
Back Thickness- Deadlifts 2x5 (straight sets heavy as possible)
Extreme Stretches
and thats it. once or twice a week throw in some weighted sit ups for abs.
I gained a little fat, so now im continuing the same diet basically (but all clean foods, more meal timing, eating carbs only postworkout and in the am) and added in some HIIT for cardio 3-4x a week. Believe me, try and stick it out for 6 weeks, you will get used to going balls out on that one set, and it feeling fucking great. I beat my previous weight in reps or im adding weight to the bar almost every week, i rarely hit a sticking point. rotate 3 compound exercises, forget about cables and "detail" work. If you follow this program to the letter im guaranteeing it works.
Heres the exercises i picked (and were approved by DC on another board) when i first started:
Chest- Smith Inclines, hammer strength flat benches, Dips
Shoulders- Smith Machine Presses, Hammer strength military presses, standing OHP
Triceps- RG benches on smith, cg benches, dips elbows in
back width- hammer strength pulldowns, cg pullups, wg pulldowns
back thickness- floor deads, rack deads, hammer strength rows
quads-squats, leg presses, hack squats
hams-lying leg curls, seated leg curls
calves- standing calf raises, seated, leg press calf raises
biceps- preacher curls, barbell curls, machine preacher curls
