The purpose of this pilot study is to evaluate the feasibility of recruiting African American prostate cancer survivors to a 12 week physical activity intervention study of three arms (aerobics, resistance training, and usual care) through physician referral and community advertisement strategies. In addition, the investigators will investigate the acceptance rate of the intervention and gather preliminary results on the effect of exercise on African American men's urinary and sexual functions. These data can then be used to refine the intervention and its implementation model, and to inform the submission of a larger grant to the National Institutes of Health.

NONE
* Physical activity questionnaire for older adults * Asks about activities in the past 4 weeks * 41 questions and asks to notate how long the activity took
* Questions about leisure time (27) and household activities (5) * Mark if participated in the activity during the past year, ages 51-65, 35-50, 23-34, and onset of puberty through 21 years
* Measures urinary and sexual function before and after prostate cancer treatment * 7 questions about urinary function * 9 questions about sexual function
Recruitment rate comparisons between physician referral and community advertisement
Time frame: Completion of study (approximately 3.5 years)
Attrition rate in each arm
* Evaluate percentage of finished duration of walking in each session and percentage of total finished session in the aerobic exercise arm. * Evaluate the percentage of attended sessions in the resistance training arm
Time frame: Completion of study (approximately 3.5 years)
Intervention effectiveness as measured by change in accelerometer measured physical activity
Time frame: Completion of study (approximately 3.5 years)
Intervention effectiveness as measured by change in self-reported urinary/sexual function as measured by Expanded Prostate Cancer Index Composite (EPIC)
-Intervention effectiveness will be compared between the three arms by comparing the change in self-reported urinary and sexual function. Mixed effects regression will be used to account for the longitudinal design.
Time frame: Completion of study (approximately 3.5 years)
