  • Athletes seeking injury-resilient strength and performance programming
  • Adults 50+ focusing on strength, balance, and fall prevention
  • Busy professionals who want high-level coaching at home or office without commuting

What’s Included in SISU Personal Training

Movement screen & fitness assessment

Each client begins with a thorough movement assessment and fitness screen so your program accounts for past injuries, current limitations, and performance goals.

Progressive strength & conditioning

Sessions blend strength training, power development, mobility work, and conditioning so you build capacity in a way that feels challenging, safe, and purposeful.

Personalized program design

Your training plan is written specifically for you by Dr. Jaasko — not copied from a template. Every phase is tailored to your schedule, equipment, and how your body responds.

Lifestyle & nutrition guidance

Receive practical, non-prescriptive guidance on sleep, stress, activity, and general nutrition habits that support your training, recovery, and long-term health.

Train smarter. Move better. Feel stronger.

If you’re ready for personal training that respects your history, challenges your limits, and fits your life, SISU Personal Training brings the gym-quality coaching to you.
