The US Physical Activity Guidelines recommend 150–300 minutes of moderate aerobic activity a week plus muscle-strengthening on two or more days, with balance work for older adults. Every longevity trend a client brings can be checked against that baseline.

Muscle-strengthening activity is associated with lower all-cause mortality in cohort meta-analysis (Momma et al., BJSM 2022). Higher cardiorespiratory fitness is associated with lower mortality in treadmill cohorts (Mandsager et al., 2018). Explain associations honestly; do not promise causation or a lifespan number.

In coaching: two short full-body sessions a week, progressed slowly. Get clinician clearance first for clients with joint problems, heart conditions or recent surgery.

Philadelphia clients may arrive with papers from PubMed or a second opinion from a teaching hospital. Your job is not to out-doctor the doctor. It is to help the client turn a clear medical plan into daily habits, and to refuse requests to source peptides, change doses or interpret labs. When a client asks "what does this paper mean for me?", help them list questions for their clinician rather than inventing a clinical interpretation.

A meaningful share of weight lost on GLP-1-based therapies can be lean tissue (Neeland et al., 2024). The 2025 joint advisory from ACLM, ASN, OMA and TOS emphasises nutrient-dense food, adequate protein and resistance training (Mozaffarian et al., 2025). The coach owns the habit layer. The prescriber owns the medicine. See coaching alongside a prescriber.

Use NBHWC scope language: educate, support behaviour change, refer. Practising medicine, physical therapy, dietetics and pharmacy are regulated in Pennsylvania (and neighbouring NJ/DE). Refuse cure claims and anti-ageing product funnels (FDA health fraud).

Center City and the Main Line see a lot of optimisation marketing. Teach a simple test: what is it, what is the evidence, who supervises it, and what does it cost compared with a year of strength coaching? Coaches never sell or source peptides, GLP-1 medicines or "research" compounds.

• Chest pain, fainting, palpitations or unusual breathlessness on exertion. With chest pain or fainting, call 911.
• New or worsening joint pain, swelling or an injury that is not settling.
• A fall, dizziness or feeling unsteady.
• Unplanned weight loss, or GI symptoms or dizziness while on a GLP-1 medicine.

1. Strength: sessions completed this week?
2. Fitness: longest walk or train this week?
3. Protein: did planned meals survive commute days?
4. Sleep: after late SEPTA / late-shift days, how was recovery?
5. Referral check: any symptoms for the doctor?

• "Can you interpret my labs / biological-age test?" "No. Bring those to your clinician. I can help turn their plan into habits."
• "Can you get me peptides cheaper?" "I don't source or sell. That stays with your clinician and pharmacy."
• "Am I too old to start lifting?" "Most people can start with a matched plan. Check with your doctor first if you have heart, joint or bone concerns."

1. Weeks 1–2: free Level 1, then Level 2. Draft scope and a referral list of licensed local clinicians from public listings only.
2. Weeks 3–6: Level 3. Practise the evidence-quality checklist on three studies.
3. Weeks 7–10: Level 4. Build GLP-1-aware strength templates and the prescriber hand-off.
4. Weeks 11–13: pilot with three to five clients. Consider whether NBHWC certification fits; it is separate from LetsGo Academy.

Start free at Level 1. Level 3 (US$300): evidence, scope, GLP-1 and peptide foundations. Level 4 (US$500): prescriber collaboration, US scope, HHS interim 503A peptide policy literacy (not FDA approval). Level 5 (US$500): jurisdiction cases. Profile: /coach. We do not promise income or client numbers.

Education only. LetsGo Academy is not NBHWC certification and does not grant any licence to practise.
