To increase your balance, try standing one-legged on a sofa cushion while passing a medicine ball from one hand to the next. This is harder than it sounds and will increase your coordination, balance and overall body control. For an advanced technique, try closing your eyes during the exercise.
Go with a friend. Studies have shown that taking someone along with you to a gym is likely to not only increase the amount of time you stay, but also the intensity of your workout. Some gyms offer discounts when multiple people register together, so take advantage of this and bring someone along!
When working out, a great tip is to be sure you warm up your brain. The reason for this is because your central nervous system lets your muscles know when to contract. One way you can achieve this is by standing on a single leg while squatting, and then touch the floor with your opposite hand.
