Parents with young children may find it difficult to exercise. Children have needs that have to be met. Instead of 
forgoing exercise it may be better to include children in your workout. Research is showing that children with active parents are more likely to be active. First it is necessary to let go of what was previously considered an “ideal workout”. Jumping and climbing can be extremely aerobic if done together. If it is floor exercises, work as partners. If the child gets bored make him or her your personal trainer in which he has to count how many reps you are doing. Children love a position of responsibility and authority. Make music a part of the workout. Speed up when certain phrases are sung. Into running? Have you child pace you as he or she rides a bike alongside of you. Make use of playgrounds. Whatever apparatus (ex. monkey bars) is there for a child can also work for an adult. Create a dance routine from YouTube videos. Children have a great deal of energy, and they should. So instead of play dates with other children make a play date with your own child. It may even make you feel like a child again.
