Books and Resources to Start Strong
Before you invest in equipment, invest in knowledge. These books address the business, coaching, and client management sides of personal training—areas where most new trainers struggle. They’ll help you avoid costly mistakes and build systems that actually work.
The Business of Personal Training by Christopher R. Moyer
This book covers pricing strategies, client acquisition, retention, and the operational side of running a training business. Most new trainers focus entirely on the coaching and ignore the business mechanics that determine whether they survive the first two years. Moyer walks through real numbers and practical decisions you’ll face immediately.

Equipment You Need
Your startup equipment needs depend on your training model. If you work at a gym, you need almost nothing. If you train clients in studios, homes, or outdoors, you’ll need to buy essential gear. This list prioritizes what actually gets used, not what looks impressive in your space.
Core Strength Training Equipment
- Adjustable dumbbells: Let you load multiple exercises without buying 10 individual pairs. Essential for studio or home-based training.
- Barbell and weight plates: If you work with serious strength clients or run group sessions. Start with one 45-lb bar, 150–200 lbs of plates, and add from there.
- Kettlebells: One 35-lb and one 50-lb kettlebell cover most client needs. Versatile for strength, conditioning, and mobility.
- Resistance bands: Compact, inexpensive, and useful for warm-ups, shoulder work, and clients with joint limitations.
- Pull-up bar: Fits in a doorway or attaches to a rack. Expands your exercise options significantly.

Cardio and Movement Equipment
- Jump rope: Cheap, portable, and useful for warm-ups or conditioning work.
- Rowing machine: Takes up more space but trains both strength and conditioning. Only if you have dedicated studio space.
- Battle ropes: Not essential, but add variety if you work with athletic or conditioning-focused clients.
Recovery and Mobility Tools
- Foam roller: Standard and trigger-point versions help clients manage soreness and improve mobility between sessions.
- Lacrosse balls: Small, portable, and excellent for targeted muscle release work.
- Yoga mats: You need at least two—one for demonstration, one for client use during stretching or floor work.
- Massage gun: Clients appreciate this, but it’s secondary to technique-based recovery work.
Assessment and Tracking Tools
- Body weight scale: A reliable digital scale. Don’t over-emphasize weight changes, but track them consistently.
- Measuring tape: Cheaper and often more useful than scale weight for showing progress.
- Heart rate monitor or fitness watch: Helps clients understand effort levels during conditioning work.
- Notebook and pen: Document every session. This becomes your best marketing tool when clients see written progress.
Studio Setup (Optional but Recommended)
- Squat rack or power rack: If you run a dedicated studio, this anchors your setup. Allows safe barbell work and pull-ups.
- Adjustable bench: For bench pressing, dumbbell work, and step-ups. Look for heavy-duty commercial versions.
- Mirror: Allows clients to see form feedback in real time. Mount safely and securely.
- Flooring: Rubber tiles or stall mats protect floors and reduce noise. Important if you lease commercial space.
What to Buy First vs Later
Start minimal and add based on client demand. This approach keeps startup costs low and lets you test what actually gets used.
- Month 1–2 (First-time investment): Adjustable dumbbells, resistance bands, foam roller, yoga mats, notebook, measuring tape. Total equipment cost: $400–$600.
- Month 3–6 (After first clients): Kettlebells, jump rope, lacrosse balls, pull-up bar. Add this once you understand your client mix.
- Month 6–12 (Scale if needed): Barbell, plates, bench, squat rack only if you have dedicated studio space and multiple strength-focused clients.
- Later (Year 2+): Rowing machine, massage gun, advanced assessment tools. Only add if clients ask or your business model supports it.
New vs Used Equipment
Buy new barbells, dumbbells, and benches—used ones often have hidden damage, incorrect weight markings, or safety issues. The cost difference is 10–20%, and your liability if someone gets hurt is not worth the savings. Barbells especially should be new. A cracked or bent bar can cause serious injury.
Buy used for: kettlebells, resistance bands, foam rollers, yoga mats, and mirrors. These items don’t wear out or degrade meaningfully. Check Facebook Marketplace, Craigslist, and local gym closures. You can often find quality equipment at 40–50% of retail prices. Also buy used for specialty items like rowing machines or squat racks after you know you’ll use them regularly.
