Im not even sure where to begin. First off, a workout should be done within 45 minute not including the warm up. Your workouts might be all over the charts for all I know, so keep a log of your exercises, sets, reps, and rest time.You probably shouldnt lift for more than 4 days a week. For your bench specifically, choose either the flat barbell press, or the incline bar press. Work up to a five rep max. Then Grab the dumbells and work the opposite angle of what you just did. Do about 4 sets 6. Every two weeks, switch to the opposite bench angles.
For your back, if you can, start with chinups about shoulder width and an overhand grip.Do 4-5 sets of what you can. Do lat pulldowns if you cant manage a chinup. Then do dumbell bent over rows for 4 sets of 10. You should go intense enough that you hate doing them.
For shoulders, work barbell militatry presses. work up to a five rep max. Then do 4 sets of 6 reps of upright rows with dumbbells.
For tricep work, do either weighted dips or close grip bench presses. Am for 4 sets of 6-8 reps. For biceps put your back against the wall to prevent swinging and do either hammer grip or traditional supinated grip curls. For the same amount of volume as the triceps.
For legs, do squats, not leg presses or machine work. Work up to a five rep max for two weeks striaght. Then alternate it with the deadlift. The secong exercise should either be a stiff deadlift or romanian deadlift. 4 sets of 6-8 reps. End with the ONLY machine work I recommend, laying hamstring curls. 3 sets of 6.
This is just a very basic general program for a newbie. Dont overwork yourself. Dont use machines. Check out this site for the proper technique of the movements i stated. Only train for 6 weeks at a time. DONT READ BODYBUILDING MAGAZINES, they are misleading supplement pro da. DONT do endless sets and reps with crappy form. LIFT HEAVY. AMEN
