This study is about how mental effort affects strength and nerve-muscle function in older adults during low-intensity resistance training. Resistance training means using exercises to make muscles stronger. Participants will be split into three groups: one doing regular low-intensity resistance training, one adding mental effort to the training, and one control group that doesn't exercise but participates in testing.

Training involves 8 weeks of exercises like leg press and bicep curls at a fitness center, twice a week. Each session lasts 45-60 minutes. Participants will imagine strong muscle contractions during exercises, even though the weights are light.

Strength, neuromuscular function, and body composition will be measured before and after the study.

• Duration: 8 weeks with 2 sessions per week.
• Training is supervised by Kennesaw State University staff.
• Participants should maintain regular activity and diet, and not miss more than 3 sessions.

To join, you need a Body Mass Index (BMI) between 18.5 and 33 and should not have exercised regularly in the past 2 years. Certain health issues may prevent participation, like heart problems or recent surgery.
