>>4188351I recently went through this. First of all get over the anxiety and just fight through it. After a couple weeks you'll feel fine going there, and you'll already feel healthier. As weak as you may be, there is always someone weaker, and they've got the balls to hit the gym so you should too. For your routine I'd recommend rotating muscle groups every day, or pairs of muscle groups. I do a cardio warmup every workout (started at ten minutes, have just made it longer as I regain fitness) and then work legs/shoulders, arms/forearms, chest/upper back, or core/lower back depending on the day. I have one day off a week. Someone here who's been at fitness longer than I (only been at this for two months) may have some better recommendations. However I'd recommend you pick a muscle group to start with, go to the gym, look at the equipment, and lookup workouts for that particular group online based on the equipment available. Free weights are preferable to most machine workouts from what I hear. Other than that, just keep at it, you can also learn other workouts from other guys at the gym who have been going longer.
