I think i want to join a gym to get into better shape but im afraid because muscle and a manly shape might happen

Just do more lower body work. Squats and deadlifts to work your booty, some cardio after to burn a few more calories for toning up. Go easy on upper body work so as not to build shoulders. As someone else said you'll get "in shape" before you start to bulk up

That’ll take some time to build up a tough physique. You’ll get toned long before you start looking “manly”. I say go for it, if you want.

You can improve your legs just by walking. Finding someone else to eat all the bread would probably help too! :-)

I can join a gym for free from work but i don't have the will or the energy. :(

Yeah,take it easy on the carbs. :)

Light weights more reps?

Best decision I ever made

Cut out carbs and sugar
