If you want to get in shape here are some things to avoid. Don't start without a plan. This can slow your progress or even get you hurt. Include stretching after you workout when your warm not before when your cold. Don't do too many sets or exercises. Start slowly and gradually increase your intensity. Push yourself hard enough to get results. Don't baby yourself. They call it progressive resistance for a reason. Vary the routine or you will never make progress. Doing the same thing for more than a month will kill one's momentum. Do complete workouts. Doing cardio alone won't develop fat burning muscles and doing quad muscles without hamstrings will create back problems. Make sure you're balanced. Be sure to maintain focus. If you move from exercise to exercise you can get done in 30 mins. If you get distracted you can talk for 30 mins. Don't drink too many sports drinks. They contain a high amount of cals. and can add unwanted lbs. Be active even when you're not working out. Even if you workout you still need to increase activity to lose weight. Shoot for 3-5 times per week to do something. Plan a balanced diet for the week on Sunday. Include lean protein and water based carbs. If you plan in advance you can often eliminate impulse eating.
