SCOTTSDALE, Ariz. -- Spending hours on a treadmill or going to the gym five days a week shouldn't be on your kid's list of New Year's resolutions.

But that doesn't mean that you can't help instill some good habits when it comes to their physical development.

"Parents play a critical role in shaping their kids' physical habits later in life," said Randy McCoy, curriculum director for The Little Gym International, a company whose gymnastics-based classes help kids between 4 months and 12 years develop motor skills and self-confidence.

The Little Gym offers these tips for keeping kids active and confident in 2007:

--Kids should try their best -- but they don't have to be the best. Parents, coaches and gym teachers should pay special attention to this one. For most kids, success is about more than winning or losing; it's about benefiting from the learning that takes place when taking on a challenge, trying their best, and having fun.

--Positive reinforcement is a must. Kids thrive in environments where they feel supported and safe. Even more importantly, kids whose physical activities take place in these environments are more likely to stick with them later in life.

--Challenge your child. It is healthy to present your child with new challenges and risks, but do so without expectations. Let them take the challenge at their own pace.

--Lead by example. Some kids aren't eager to try new physical activities. To encourage them, don't demand; demonstrate the skill yourself, provide positive motivation, and your child will likely want to give it a try.

--Repetition, repetition, repetition. Repetition of a skill is necessary for the child to internalize and eventually master it. It also gives a child more opportunities to experience success, build confidence and develop strength and endurance.

--Safety matters. If your child is participating in organized physical activities, make sure they are led by trained instructors. Sports equipment should be appropriately sized for children.

--Don't mistake your child's physical development for Olympic training. Your child might be the fastest runner in their class, but that's not a reason to pull them out of other activities to pursue a gold medal. At this age, the focus on physical activity should be fun and health -- not fame and world records.
