This seems like a decent plan but you may not need a full hour just to do upper body in the gym. You need to identify key workouts for each muscle group and don't over do it. Make sure you have a day in between each gym visit. High weight-low rep excercises are better for gaining muscle. Basicly you need to tear the muscle so it heals larger. Don't be intimidated by all the nobs at the gym. Just do what you want to do. My typical upper body workout consists of bench press, bicep curl, horizontal row, tricep extension and pec fly. Typically three or four sets of 5-8 reps with a weight aimed to really struggle on the last set. Again, don't be pressured into putting the weight up too soon. Once you are comfortable, increase the weight and also change excersises or you won't see any benefit.Stollos said:My plan is to ease into a routine of morning walks and jogging for 4 consecutive days of the week, and then 1 hour in the gym on the other 3 days. This is because my gym access is restricted to Monday-Tuesday-Wednesday. I intend to use my time at the gym to train my upper body strength, and my other days to train my legs and lower body (stomach crunches, situps, squats etc). I'm still trying to find a good route to use on my morning walks with jogging in mind (as I said, very hilly).
I hate jogging so I won't give you much advice on that. I do like interval training. You have say six equidistant points and sprint between them (i.e. point 1, point 2, point 1, point 3 etc). I do reccomend doing a high intensity sport if you have time. I play football but my main workout is squash. I play at least 3 times a week and its really good for your legs (lots of changes of direction etc).
In terms of diet it is important. Don't eat more than you burn. Don't eat too little or you won't gain muscle. Do eat meat. The protein is important. Eat lean red meat (good), fish (very good) and chicken (excellent). Stay away from carbohydrates as much as possible (in particular late in the day when there isn't time to burn it all off).
Most important. Get lots of sleep. This is when your body recovers (and rebuilds muscle).
Good luck!
