Brief summary: The aim of our study is to compare the effects of two different squatting patterns, with and without the knees passing the toes, on low back pain, muscle strength and balance.

Detailed description: A total of 60 volunteer participants between the ages of 18-30, who are in the active category of the International Physical Activity Assessment Questionnaire Short Form, are planned to be included in the study. Individuals participating in the study will be divided into 3 groups using a computer randomization system and a closed envelope method. Group I (n=20); squatting with the knees passing the toes (PI), Group II (n=20); squatting with the knees not passing the toes (PG) and Group III (n=20); control group (CG). Squatting with the knees passing the toes (PI); squatting with the knees not passing the toes (PG) will be applied to the study groups as a home program for 4 weeks and will be checked with an exercise diary. Participants will be re-evaluated at the end of the exercise program. No training program will be applied to the control group and they will be asked to continue their daily lives and participants will be evaluated at 4-week intervals. The training program of 1 set; 20 repetitions; 30 seconds active contraction/30 seconds rest is applied to the PI and PG groups 3 days a week, every other day for 6 weeks. The training program of the groups is monitored by a physiotherapist for 6 weeks via telerehabilitation technologies. All participants will be evaluated for back pain, knee pain, muscle thickness, muscle strength, function and balance before and at the end of the program and the data obtained will be recorded.
