1. Doing Too Much Too Soon
Some
soreness is normal but if you can't function, you went too far. Tips for getting started:
Keep it simple. Even if you used to lift weights, your body needs time to adapt. Start with 8-10 exercises and do 1 set of 10-12 reps for the first week or so.
Rest. If you feel sore, give yourself extra recovery days. You may need a few weeks of consistent exercise to build a strong foundation.
2. Holding Onto the Treadmill for Dear Life
Holding on puts your body in an unnatural position that could strain the shoulders. It can also affect posture and reduce the calories burned.
Keep in mind that it's not just the treadmill. Avoiding the rails on any machine will help you improve balance, burn more calories and move in a more natural way.
5. Bouncing When You Stretch
6. Doing the Same Thing Over and Over
Always allow an extra 5-10 minutes before the workout and warm up with a little light cardio.
