No. You can either purchase an assessment individually, or you can begin our proof30 (day) Experience where you receive 2 coached proof360 Assessments, a Personal Training Session, a personalized Lifestyle & Nutrition Strategy, and 30 days of our small-group class training.
No pressure. You can take your results and walk away—or use them to start progressing with us.
Wear comfortable clothes and athletic shoes. No need to stretch or warm up beforehand—the assessment is low-impact and guided by a coach.
You will put effort into the strength and power test, but the total effort time is only a few minutes.
Your first proof360 Assessment takes about 60 minutes total: 30 minutes to complete the assessment, plus 30 minutes to review results with a coach. Subsequent assessments take between 30 and 45 minutes.
We recommend a full proof360 Assessment every 3-6 months to capture meaningful changes in strength, mobility, and performance.
