Luckily, there is an exercise room in my apartment, which I use only for aerobics (running on a treadmill, occasionally the stairmaster or bike). My weight routine is accomplished in the comfort of my own apartment, and includes: - Pull-ups and chin-ups, using a bar that fits over the bathroom door frame - Pushups (regular, and "Fury," or "Hindu," pushups) - Squats (no weights, just lower self to ground) - Occasionlly, ab crunches and situps I've gotten compliments on my upper body since starting to do the pushups and chin-ups/pull-ups religiously. I never spend more than a few minutes per day doing bodyweight exercises but it pays off and the convenience of being able to do this at home is one reason why I am able to stick with it. I feel this is much more efficient and effective than going to a gym. Well it very well could be more efficient, but it's definitely not more effective. If you just have your body, and you really don't want to use any equipment (a dynaband is great for arm, leg, and rotator cuff muscle light workouts), consider doing plyometrics. You aren't going to work your lower body sufficiently just doing squats, but if you have a stable, low bench or something you could get a lot more out of your lower body workouts. Also consider squat-jump-thrusts (a burpie with a vertical jump at the end) performed plyometrically. There are tons of good body weight exercises for your chest, abs, and lower body if you need any suggestions.
