Starting a workout regimen
 

So I have had some changes in my life recently (my fiancee leaving me but that's not the point) and I want to start a workout regimen. I have taken weight training courses in college but I have let myself go for about 2 years. I have been running twice a day on a treadmill for a short period of time and today I will be joining a gym. I was wondering if the following would be a good workout schedule. It's an 8 day schedule. Also for a little bit of information, I am 23, 5'11" and weigh 135 lbs. I'm sure I will have to start out slower than this but would this work as a goal for a schedule?

Monday Cardio and Abs
30 Minutes of High Intensity Cardio
2 sets Hanging Leg Raises
2 sets Hanging Knee Raises
2 sets Russian Twists
2 sets Raised-Knee Crunches

Tuesday Chest/Triceps
3 Sets Bench Press x 8-10 reps
3 Sets Incline Dumbbell Press x 8-10 reps
4 Sets Cable Crossovers x 10-12 reps
3 Sets Overhead Tricep Extension x 10-12 reps
3 Sets Cable Pull-Downs x 12-15 reps
3 Sets Lying Tricep Extension (skullcrusher) x10-12 reps

Wednesday Cardio and Abs
Same as Monday

Thursday Rest Day

Friday Biceps/Back
3 Sets Standing Dumbbell Curls x 10-12 reps
3 Sets Preacher Curls x 10-12 reps
2 Sets Reverse Grip Pull-Ups x max reps
3 Sets Seated Cable Rows x 10-12 reps
3 Sets Single Arm Dumbell Rows x 10-12 reps
3 Sets Wide Grip Pull Downs x10-12 reps

Saturday Cardio and Abs
Same as Monday

Sunday Rest Day

Monday Shoulders/Legs
4 Sets Leg Press/Squats x 8-10 reps
3 Sets Leg Curls x 10-12 reps
3 Sets Stiff Leg Deadlifts x 10-12 reps
3 Sets Shoulder Press x 10-12 reps
3 Sets Side Lateral Raises x 12-15 reps
3 Sets Upright Rows x 10-12 reps

And then I would start again from the beginning on the next day. I don't know if this would be a good way to start out or if it might be too much or not enough. I was also thinking of maybe just cutting out one day of rest and making it 7 days. On my rest days anyways I plan on running. I plan on using dumbells for the exercises that I can. Any tips would be very helpful.

That seems like a very good start. If you're 135, I'd strongly suggest increasing your food intake. Coupled with this exercise regiment, you could see very real increases in body mass while still maintaining a healthy physique. Just remember to get your proteins, fats, and carbohydrates from healthy foods!

What is your goal? If you're looking to add bulk, you need to cut back on the reps/sets. If you're just looking to stay lean with light weight and high reps, its fine, but I'd start off a bit slower.

I am wanting to add a bit of bulk but not too much. I have a thin frame and I kind of like that. I want to add strength and more tone with a bit of bulk in my arms and chest mostly.

This is a problem I have had for a long time. I eat quite a bit but i must burn it off quickly because I can't put on weight. I also never really learned how to gain weight through food in a healthy manner. It's definitely something I should start looking into.

I'm the opposite of this. I need to work really hard to keep from bulking up.

My suggestion would be pretty straight forward: eat. Have a large breakfast that has plenty of fiber (oatmeal, whole wheat toast, whole wheat cereal), protein (think turkey sausage, eggs, lean ham, milk, etc.), and don't forget your multivitamin. I do not suggest any caffeine. If you have trouble waking up in the morning, go to bed earlier and exercise in the morning. Meal 2 would be about 2.5 hours after breakfast and should have more protein and healthy carbs. Lunch should be a balance of protein, carbs, and fats, maybe a sandwich and a v8. Afternoon snack should be maybe a protein shake. Dinner should be kinda small. Maybe a chicken breast, 1/2 peas, and 1/2 cup broccoli. Then have a snack of dried fruit and nuts about 2.5 hours before bed.

I started hitting the gym again two weeks ago. And I was in your situation when I was 20 at 125-130 lbs, but went up to 145-150 by 22 through exercising.
The only changes I would suggest is to do abs everyday as a warm up and come up with an ab routine. Bicycle crunches, weighted situps, leg lifts,... I would also recommend changing exercises and doing them all in different orders each time you are at the gym.

My routine for the next 6 weeks will be this:
Monday Cardio(Run) and Abs
Tuesday Chest/Triceps
Wednesday Cardio(Swim) and Abs
Thursday Biceps/Back/Shoulders
Friday Cardio(Run) and Abs
Saturday Cardio(Bike) and Legs
Sunday Rest Day
