Beginner. ..Need some help/tips

Listen to your body about the calories if you feel you are putting not putting on muscle then increase calories by 250 and see if thats better and how long you train doesnt matter as long as you ate a good meal before so your body does not use your muscle as fuel just have a nice meal before like eggs and oat meal mabye a few sausages or something with it and then in about half an hour or an hour go work out and have a protein shake or a meal after your done even if you spend hours in the gym its okay train hard you wanna go until failure and find a weight you can do at least 5 reps or more and barbells are better then dumbells but dumbells are okay just grab one it each hand and do a soupanation curl and you can work a lot of your body with dumbells you can work your biceps triceps quads and even back just about every thing with just a pair of dumbells ill comment again after i look at your weight then ill tell you how many grams of protein carbs and fats you should be taking and ill post a video so you know what soupanation curls are

If i were you i would aim for 3000 calories , 150-200 grams of protein per day , about 300 carbs , a 100 grams of fats and 157 grams of sugar .. the sugar isnt important you dont need the sugar it doesnt benifet you in a good way but if you want a treat its fine but carbs are mainly used for energy try to get complex carbs like whole wheat bread rolled oats and stuff like that those are good carbs , protein is a must for adding muscle protein gets converted to amino acids that help rebuild your muscles and help you grow and fats are good for horomone production all fats are good except trans fats .. trans fats are the only bad kind of fats and if you add this to your my fitness pal and you try it and it isnt working for you then add 250 more calories and please dont expect results right away like in a week or two you will be built like a brick house it takes time and you gotta stick to what your doing stick to your work outs and your macros you will see results over time your strength will go up your muscle size will go up and i must stress this again find a weight you can perform about 8 reps with that you struggle to get all the reps with about 8-12 would be a good range and if you wanna look into buying a protein shake or some kinda supplement let me know because a lot of products are all scams or garbage theres good products out there and online is the best place to get them cheap

I looked at the titles of the videos i think i have seen them both a long time a go but i dont like that six pack short cuts guy i think he is a scam trying to make money off people but i digress ... As for the dieting thing unless your planning on being a model , body builder or a professional athlete then you dont have to worry about never touching sugar or this or that ... If you are just a regular guy trying to get in shape then you dont have to deprive your self of sugars , trans fats , fast digesting carbs (white rice , white bread ect) Just have all of that kind of stuff in moderation be conscious of what your consuming dont have a sugary treat every day but every week is great . If your at diner and there is white bread or you just like white bread dont worry about it or your going out to eat at like a damn mc donalds or some thing thats fine just dont make it often and a pattern . Try to eat clean but if you want some thing just for that one time dont worry about it and if your going to have some thing that is ''bad'' just try and keep the portion down but try and eat clean the majority of the time . (Steak , chicken salmon brown rice beans ect )

Compound movements are the best for muscle growth and you can see a lot of strength gains too but isolation work can be use full as well to fill in the cracks . I have not touched a bench press since i was about 14 years old and the bench press is on of the best ways to build up your chest (Depending on your grip whether it be close grip or a wide grip ) but i did chest flies cause that was all i could do and i built a gorilla like chest from just doing chest flies on the floor . Basically use compound movements for every thing and isolation if you or your gym dont have what is needed you can get where ever your trying to go with isolation work its possible . Overall compound movements are best . As for the best muscle building moves compound movement like dead lifting , bench pressing , squatting rowing some thing that takes more of your body parts or muscles to do the exercise the compound movements i listed are the best exercises ever for gaining muscle and if you wanna do any cardio i would just walk or go at a moderate pace on an elliptical or some thing if your doing high intensity cardio you can lose a lot of weight and often its all muscle thats lost

I have a question also did your doctor say you have Low T or do you suspect it ? And adrenal issues like your adrenalin glan burned up ? Also sorry for the long answers and im working on the punctuation . And by lifting heavy you can boost your testosterone i dont know by how much but your body starts producing more when lifting heavy

is 2830 your maintenance level calories? If yes, I would say cut to 2330 and eat in 500 per day deficit until you get to sub 15% body fat..

^shouldn't he be eating at a surplus, or at least maintenance if he wants to gain muscle mass and is worried that he has lost muscle.
185 and 6'2 sounds pretty lean to me.

Would doing all these exercises at one time be too much overkill?

One-Arm Dumbbell Rows
Dual Dumbbell Rows
Braced Dumbbell Rows
Incline Dumbbell Press
Flat Dumbbell Press
Incline Dumbbell Flyes
Flat Dumbbell Flyes
Decline Dumbbell Press
Decline Dumbbell Flyes
Seated Dumbbell Press
Standing Dumbbell Press
Dumbbell Side Laterals
Dumbbell Rear Delt Flyes
One-Arm Dumbbell Clean and Press
Dumbbell Squats
Dumbbell Lunges
Dumbbell Step-Ups
Dumbbell Split Squats

Yes... Doing all of that in one workout is going to be way too much!

Check out this site http://www.aworkoutroutine.com/
It has some very good beginner routines and a ton of good info...

Out of all the exercises you listed the only ones you should do are dumbbell rows (one in each hand) you could do a dumbbell press whether it be incline or flat thats your choice i would stick with one or the other and go through my sets like that as for flies id just do them flat throw in a shoulder press keep the rear delt flies and larerial raises and a dumbbell squat i would do bicep curls and some skull crushers at the end of the work out i like to train arms last because if you train them first you get fatigued and then you cant do the other exercises as good if you wanted to you could throw in wrist curls at the end of the work out my fore arms have gotten massive from doing them but all the exercises are above would be great for a beginner you could do all those exercises for your first 2 years of training .. its good to stick to the basics and not venture out and do exercises for advanced lifters people think oh i need to do this exercise and get this head of my tricep bigger when there arms are small if you stick to the basics you can get huge if you feel like you wanna work on a certain head of your arm or some thing and youve worked out for years then go ahead i think you should do what i recommended if you wanna do some other program thats your choice but i told you every thing you need to know
