Help with my Routine!!!

So, i want to define a routine and stick to it for great results. I already know most of the "tips" (eat well, protein, warm up etc.)

*I can only go to GYM on Tuesdays and Thursdays (might start going Mondays too if its needed) Also, at home all i got is a Dumbell (changeable up to 25 kg i think)

So what im currently doing is always sets of 4 (one warm up 30%, 3 100% (% meaning weight of fail about at 12 reps)) and i do them with weight that makes me fail at about 12 reps. Drinking 100% whey after workouts. Always eating good meat + nutrients.

Tuesday:
Chest/Tricep
Thursday:
Bicep/Back/Shoulder
---> Great ab routine each 2nd day (Tue, Thur, Sat)

But if i staying Mondays too (im not really sure if i could) it would look something like this:

Monday:
Tricep/Chest
Tuesday:
Legs/Shoulders
Thursday:
Back/Biceps

Also, im wondering, wouldnt doing these kinds of routine (which were recommended to me btw) only workout your muscle one day of the week? Which seems kinda few to me. Also, wouldnt it be better to switch, for example, Bicep with Tricep, so that TUE i do Bicep/Chest and THURS i do back/Tricep? (Since for example on Chest excersises, you also secondarily excersise tricep, atleast thats what i think, so youll be working triceps both TUE and THURS) ?

Last, how much should i be resting between each set of reps? Im doing like 10-20 secs, cause i cant really find the answer...

Sorry if this is kinda long, but this is very important to me

- you should go for full body workouts x 3/week
- maybe go for a heavy, moderate and light session doing the heavier one's at the gym and the lighter one at home for equipment reasons

You can do full body workouts 3 times a week as swanso5 recommended or do 2 split routines on gym days. I like doing chest and lats the same day because they are a system, add abdominals. On day 2 do shoulders, biceps and triceps. I recommend 4 sets of each exercise, 2 exercises per body part. Set 1 8-10 reps, set 2 6-8 reps, set 3 4-6 reps, and set 4 20+ reps. Last two sets to failure.

On a third day you can do a home workout (3 sets as many as you can do for 30 seconds) of push-ups, pull-ups, and 2 of the following alternated each workout, squats, lunges, step-ups and dumbbell deadlifts.

Lastly, the amount of time you rest depends on your goal. If you want strength you need to rest about 3 minutes between sets, size 60 - 90 seconds, a bit of size, strength, and great conditioning 30 seconds.
