Parkinson's disease is a condition that affects movement and can make it hard to walk or keep balance. This study is testing different ways to help people with Parkinson's improve their walking and balance by using certain instructions called *focus of attention*. These instructions help the brain learn how to move better. Internal focus means paying attention to your own movements, while external focus means paying attention to things outside your body. The study will see if combining these helps more. People in the study will exercise for six weeks, three times a week. They will be in one of three groups: a combined focus group, an external focus group, or a control group that gets no special instructions. They will be checked before and after the program to see if their walking and balance improve.

• The study lasts six weeks with three sessions per week.
• Participants are people aged 50-70 with Parkinson's but no severe walking issues.
• You'll be part of a group that follows specific focus instructions or a control group.
