Start with a conversation
What do you want to change?
A free 30-minute video consultation gives us time to understand your goals, your routine, and the coaching that fits you.
Tell us a little about your starting point, then choose your call time on Calendly. Your answers will be included in the booking notes.
Before you start
Your questions, answered.
Do I need to be fit already?
No. We begin with your experience and goals, then adapt the exercises and pace to your starting point.
What happens during the free trial?
Start with a free 30-minute video consultation. If PHI is a fit, arrange two free 1-hour training sessions to experience the coaching. One trial per new client, subject to availability, with no paid package required.
Which session length should I choose?
30-minute sessions suit a focused workout. One-hour sessions give more time for coaching and a broader program. We will help you choose based on your goals and schedule.
Where do sessions happen?
Discuss in-home options in Brooklyn or Manhattan, or gym-based training where venue access is available. Confirm the location and any venue fees before committing to a package.
Is this physical therapy?
PHI provides fitness coaching, not physical therapy or medical treatment. Return-to-exercise training follows completed rehabilitation and any relevant guidance from your healthcare provider.
Can I buy online?
Yes. Choose a package to pay securely through Stripe. Confirm your training location and availability with Marc before buying. Payment is a one-time purchase; scheduling is separate. Your sessions are arranged after payment is confirmed. Eligible new clients can use PHIFIRST for 10% off their first multi-session package.
