The aim of this study is to evaluate the effect of a customized corrective exercise program on back pain, kyphosis degree, and quality of life in healthy adults. Our hypothesis is that healthy adults participating in a customized exercise program will show a reduction in back pain, a decrease in thoracic kyphosis angle, and an improvement in quality of life in the post-intervention period compared to the control group. The program will continue twice a week for four weeks.

Inclusion Criteria:

• aged 18-45 years

• Volunteered to participate

Exclusion Criteria:

• Individuals with orthopedic problems such as scoliosis or spondylolisthesis, those with acute infections or oncological, neurological, and rheumatological problems, and those already participating in a regular exercise program were excluded.
