it did..so i didint work biceps for the period i rested..just let it recover..as long as ur hitting the weights hard ur arms will grow..i mean biceps are only a small portion of ur arms..dont sweat over it
no idea..prolly like 20lbs or something..lol..20kg is 44lbs brah..i couldnt even chest press that when i started..

The sets and reps are different for different types of exercises, I think, and 20 mins is a bit too short IMO, maybe you're doing them too quick, remember to contract and feel the muscle you're working on, maybe like 3 secs from start to apex, then 2 secs go back down to starting position something like that, no point swinging weights that are too heavy using momentum or anything like that.

For me, the weights part of my workout takes close to 45 mins - 1 hour, compared to my cardio of 20 mins sooo it's either your exercises are too little or you're doing it them too quickly. And wait, 1 hour of cardio? O_O that's a bit too long for me.. I do my cardio just to warm up

And I can see that you are hitting all your body parts in every workout? For me, I do separate muscle groups each day, making sure to hit every one of them at least once weekly. If you do the same routine everyday, your muscle adapts and the workout becomes less effective. Swap them around to shock your muscles, and it's a good idea to only do 1-2 muscle groups in a day because you get to let them rest for few days to grow and repair while you're hitting other muscle groups.

E.g. you can follow the program I'm following, it guides you on a day-to-day basis. Kris Gethin's 12 Weeks Transformation Program

this might sound a bit harsh, but if you dont like doing weights, why do it? and for your routine, after every set are you even out of breath?

if you wanna do weights, go all out. its just gonna be a waste of time otherwise.
edit: i dont know if you guys have seen this thread, but      . i literally had nothing to reply with.

this is real old school man, I barely see this nowadays. like mihawk said, multi-station. It has lat pulldown, lying ham curls, leg extensions, shoulder press/bench press. I just glanced at it. The ones I used to see has a romanian chair, sit up bench and a pull up station too.
