Need some motivation for a college student

Have you tried a gym like Curves where it's a female-friendly atmosphere? I've noticed at Curves that there's generally women there from all age groups (I've personally always found working out around men to be the most intimidating part).

Or, at your regular gym, what about going during "off" hours when you're able - at least until you get yourself more comfortable with it?

And hell, I suffer from social anxiety; does your school offer any sort of free and/or discounted healthcare? If so, using a MILD anti anxiety (like a very low dose of Xanax or Ativan) may be enough to get you over the hump. Ideally you only want to use this short term & not have to rely on it every time you go to the gym, of course.

Workout in your room! You don't need a whole lot of space and you can choose any 30-minute amount of time your roommate is gone to do this workout! Get some dumbbells, throw on some music, do some mountain climbers (I start with 25), do some exercises to work your thighs, arms, back, abs. I like to do a circuit 'cause it's quick but burns GOOD calories and works your whole body if you have a good variety of exercises. I usually do something like this:

25 mountain climbers
10 plie squats 10 lb weight
15 military presses with knee kick 5 lb dumbbells
10 sumo squat w/ concentration curl 8 lb dumbbells
25 crunches
3 sets of 10 scissor kicks at different heights starting with highest then going to lowest
15 pelvis lifts with knee crossed over, then switch sides
REPEAT

25 mountain climbers
10 hammer curls 10 lbs
21s 8 lb dumbbells
10 swimmer presses 8 lb dumbbells
20 tricep extensions with resistance band
20 rows with resistance band
15 chest press 5 or 8 lb dumbbells
15 pec fly laying down 5 of 8 lb dumbbells
REPEAT

25 mountain climbers
10 tricep presses 10 lbs
10 overhead shoulder press 10 lbs
10-15 side bends with 10 or 25 lb dumbbell

I can't think of some of the names of these so I'm going to describe them. Hold one 10-lb dumbbell in both hands, one hand on each end. Stand straight with arms in front of you, resting on your legs, then bring up so that palms are facing down and arms come up above your head forming a straight line from your arms to your toes. Do this for 10 reps. For the next exercise, I take 2 8-lb dumbbells, one in each hand, stand with arms down at my sides and then lift up so that you're making a "T" with your arms and body. I aim for as many as possible, I'm up to 6 so far. I think that's about it, just repeat that circuit again.

Grab some buds and walk the Ped Bridge. It only feels like fun not work! Except Idk if it's open...flood and all...but ya other than that I just go for walks mostly. Put in some ear buds and crank it. I hate when people stare at me when I am out walking, but hey for all I know they are checkin out my "skinner" self. At least, that is what I tell myself =D
