Well, I'm going to make an assumption here. Seeing as you quit where you quit, you might make less of an hour long work out compared to someone else. Your drive may not be as intense during a workout.
Define drive for me please. I think I did do a decent intense workout. I would start off with running on the tread mill, and then after 20 minutes, do 3 sets, 10 reps of bicep curls, Bench press, Shoulder lifts, and some other exercises which I have no idea what their names are, but which my cousin had taught me to do. Really, I don't try to take a break between sets. I usually end off my workout on the bike.
Working out at home without weights is nigh impossible, at least for anything strength related. I do about 150 pushups (2 sets of 75) before I go to bed usually, but I don't think it helps all that much except for doing pushups.
Would crunches or squats help me improve my strength of abs and legs respectively? I could easily do those at home.
As far as getting better endurance, the answer is simple. You simply run more. There are several schools of thought regarding endurance. The first one (and the more traditional one) is simply to run longer distances, increasing the length as you become more in shape. The second one is to run a shorter distance (for me, this is 3-4 miles) at a high intensity. Both seem to work, although the latter will make you feel like puking if you do it right.
I am, in short words, a horrible runner. In grade 11, the last time I did the beep test, I managed a 8.5 and a 9. I have no idea what kind of running state I am in right now, but I imagine it's not that good. So essentially, just keep running longer distances, without stopping?
Sheer speed is a much trickier matter. Overdoing long distance cardio work can actually be counterproductive, as they operate on two different muscle fibers (fast twitch vs. slow twitch). You can still do both, but you have to know what you're doing. I suggest taking a look at plyometrics and other explosive exercises.
Alright thanks for the advice.
Gaining weight is a hard thing to do, at least as far as putting muscle mass on goes. I suggest just eating and lifting. I have this problem if I ever need to gain weight.
People sometimes talk about a ratio of carbs, fats and proteins, for one to gain weight. Should I try that? Or no.
