Simi Valley, CA

Personal trainer in Simi Valley

Simi Valley sits just over the Simi Hills from Oak Park and Thousand Oaks, and James trains clients at home there.

In-home training suits Simi Valley well: no gym to drive to after a long day, and a coach who arrives with a session already written for you. James coaches weight loss, muscle building, boxing and striking, and most clients end up mixing them, strength one day and pads and conditioning the next.

Every session is one to one and runs an hour. The first one is about how you move, your goals and anything that hurts; after that the plan follows you, adjusted as you progress. Clients of every age and starting point train with James, and the reviews on this site say it in their own words.

Sessions run Monday to Saturday, 9 AM to 6:30 PM. Call or message 541-331-0252 to find a time in Simi Valley.

  • Weight Loss Training built around losing fat and keeping it off, rather than around a single hard month. Sessions are one to one and the plan moves with you.
  • Muscle Building Strength and size work programmed session by session. Technique first, load second, so the lifts stay available to you for years rather than weeks.

  • Striking Coach For anyone who already trains and wants their striking coached rather than supervised. Rounds on the pads with real feedback between them.
