What to Expect
**Initial Consultation and Fitness Assessment**: New clients meet with a trainer for a comprehensive evaluation that includes current fitness level, medical history, weight loss goals, and any medications or treatments they're currently using. This 60-90 minute session establishes baseline measurements and identifies any physical limitations that need accommodation.

This includes selecting appropriate exercises, setting realistic milestones, and establishing a sustainable workout frequency that clients can maintain long-term.
**Progressive Training Implementation**: Clients begin their structured program with close supervision to ensure proper form and technique. Initial sessions focus on building foundational strength and cardiovascular fitness while avoiding injury risk that could derail progress.

**Lifestyle Integration Coaching**: As clients develop physical fitness, trainers provide guidance on integrating healthy habits into daily routines, managing plateaus, and maintaining motivation during challenging periods of their weight loss journey.

Insurance & Pricing
Most health insurance plans in California do not cover personal training or gym memberships, even when provided as part of a weight loss program. However, patients may be able to use Health Savings Accounts (HSAs) or Flexible Spending Accounts (FSAs) to pay for services if they have a doctor's prescription for exercise therapy as part of medical weight loss treatment. Some employers in the San Francisco Bay Area offer wellness benefits that provide partial reimbursement for gym memberships or personal training services. The insurance checker can help determine what coverage options might be available for fitness-based weight loss services.
Out-of-pocket costs for personal training typically range from $75-150 per session in San Francisco, depending on session length and package deals. Many weight loss clients find that investing in 2-3 sessions per week initially, then reducing to 1-2 sessions for maintenance, provides the best results. The clinic may offer package pricing that reduces per-session costs for clients committing to longer-term programs. Additional costs might include gym membership fees and any specialized equipment recommendations. The cost calculator can help estimate monthly expenses when combining fitness training with other weight loss treatments like GLP-1 medications.
First-Time Patient Tips
Before your first visit to Fortitude Fitness, gather information about any medical conditions, current medications, and previous injuries that might affect your exercise program. Bring a list of your weight loss goals, current activity level, and any treatments you're receiving from other healthcare providers, especially if you're using GLP-1 medications like semaglutide or tirzepatide. Wear comfortable workout clothes and athletic shoes to your initial assessment, as you'll likely perform basic movement tests and possibly a light workout to evaluate your current fitness level.
Come prepared to discuss your schedule realistically, including work commitments, family obligations, and other factors that might affect your ability to maintain a consistent exercise routine. Be honest about your past experiences with fitness programs, what has worked, what hasn't, and any concerns you have about starting a new program. Ask about their experience working with clients who have similar goals to yours, how they track progress, and what happens if you need to modify your program due to plateaus or changes in your medical treatment. Most importantly, set realistic expectations about the timeline for seeing results, as sustainable weight loss combined with fitness improvements typically takes several months of consistent effort.
