How to choose the best personal trainer for your goals

1. Training environment. Do you prefer total privacy (Parker Cote), a structured science-backed studio (First Guess Fitness), or a vibrant community space (Ethos)?
2. Coach qualifications. Look for accredited certifications (NSCA, NASM, ACSM) or degrees in exercise science and behavioral psychology rather than basic online credentials. Coaches at First Guess Fitness hold master's degrees and PhDs.
3. Program continuity. Choose studios that track progressive overload (reps, sets, and load) over time instead of guiding you through random, unstructured workouts.

Frequently Asked Questions

What is the average cost of personal training in Boston?

Personal training in Boston typically ranges from $80 to $180+ per hour for 1-on-1 sessions, depending on the studio's location and the trainer's experience. Semi-private strength training often provides identical programming and supervision at a lower monthly rate.

Where is First Guess Fitness located?

First Guess Fitness is located at 30 Court Square, Boston, MA 02108, serving clients in Downtown Crossing, Government Center, the Financial District, Beacon Hill, and surrounding neighborhoods.

What is the difference between 1-on-1 and semi-private personal training?

1-on-1 training provides exclusive one-trainer-to-one-client attention. Semi-private personal training assigns individual programs to small groups (typically 2 to 4 people), so you still get hands-on form coaching and tailored weights at a lower cost per session.
