Impressed by the coaches' work with my boys, I joined the adult program. Tailored to my needs, it's revitalized me. Starting gently, I've seen significant gains and eagerly anticipate each workout. Just three hours a week and the results are fantastic. Their nutrition plans have also helped me make sustainable diet changes. Their expertise is unmatched.

Who is adult personal training for?
TNL’s semi-private personal training is specifically built around busy adults over 40. It combines a custom training plan with coaching, accountability, and a positive small-group atmosphere.
How is semi-private training different from a group class?
Each member receives their own personal training plan. You get personalized coaching and attention while training alongside other members, rather than everyone following the same workout.
What does athlete development focus on?
The Elite Athlete Development Program focuses on speed, strength, movement technique, and sport-specific conditioning. Coaches assess each athlete and guide them through a 13-week seasonal training block.
What if my schedule changes?
The adult program offers flexible scheduling. Talk to a coach about current session availability and how training can fit your week.
How much does training cost?
Program prices are not published on the original TNL website. Contact a coach to discuss the training option, schedule, and current pricing that fit your goals. Your initial evaluation is free.
Where is TNL Performance located?
You’ll find us at 273 Whitehead Road, Hamilton, NJ 08619. We work with adults and athletes across Mercer County, Central New Jersey, and Pennsylvania.
