I'm a 22 year old male currently employed as a Program Developer(sedentary work).I weigh 110Kg's and am 186cm's high. I started working out about last week. I normally do 30mins of cardio on bicycle or treadmill, followed by 30mins of weightlifting.
My Questions: Is it better to focus on one group of muscles each day of weightlifting?
Do you think I should do more cardio than 30mins, if I can hold it?(Time is currently not an issue, but seeing as I just started last week I felt really exhausted after 30mins)
What is a good set of reps and amount of sets for building muscles?
How often should I increase the weight I'm lifting?
What do you think is a reasonable weight I should achieve after 6 months considering I also lowered my caloric intake to the recommended 1.9k and using myfittnespall to help me track everything i eat?
Last of all I have to admit I'm currently hooked on diet coke, and as much as I know it's extremely unhealthy feel I couldn't do this without it. do you think it can also hinder my weight-loss?
3 months and 1 week EDIT:
I don't really know the protocol on this things but i really wanted to thank you all for your answers and comments. As of today I have reached a Body-Weight of 98 KGs and most improtantly my muscle resistance and mass has clearly developed alot lowering my bf percentage to an estimated 20%(tape measurements). Thank you once again for your guidance through this new stage of my life.
PS: I know it doesn't look like it but I'm the OP.
