Strength Training in Vallejo — Structured for Real Life
Gymnanigans is a private strength and movement studio in Vallejo, CA, led by Donna Medina.
Every client begins with a one-on-one strategy session and professional movement assessment. From there, training progresses into structured strength and nutrition programs designed to build real strength, coordination, and long-term physical capability.
Training is individualized and intentional. Strength work, boxing-based movement, and mobility are used as tools — not trends — to help women move better, feel stronger, and stay capable in everyday life.
This is a focused, respectful environment for women who value professional guidance, clarity, and a structured path forward.

How It Works
Step 1: Schedule Your Intro Session
A focused one-on-one session to review how your body is currently moving, talk through your goals, and discuss what your next step could look like.
If you decide to move forward, we’ll outline the 6-Week Strength & Nutrition Program and how to get started.
Step 2: Begin the 6-Week Program
Start structured, personalized coaching that includes weekly in-person training, app-based workouts, and nutrition guidance. Every session builds on the last....no random workouts.
Step 3: Continue Your Progression
At the end of six weeks, you’ll review your progress and choose your next step. Many women continue into a longer-term strength program to deepen results and maintain momentum.

What Clients Say
“After a few sessions I started moving better in everyday life. I didn’t expect that — I just wanted to work out. Donna connected the dots for me.” -Trulisa
“My balance and strength have improved so much. The boxing footwork made me sharper and more coordinated.” - Janet
“I finally feel strong again. Not ‘gym strong’ — real-life strong. Donna teaches movement in a way that just makes sense.” - Denna

Common Questions Before Getting Started
Do I need to be in shape first?
No. Training begins with how your body moves right now. The program is structured around your current ability and progressed intentionally from there.
What happens during the Strategy Session?
You’ll go through a focused movement assessment, discuss your goals, and map out the best starting point for you. If the 6-Week Strength & Nutrition Program is a fit, your session fee is credited toward enrollment.
What if I have pain or a past injury?
That’s common. Many women I work with are managing something. Training is adjusted to respect your body while improving strength, coordination, and movement quality.
Is this physical therapy?
No. Gymnanigans provides structured fitness-based coaching. If medical or post-rehab exercise is needed, I’ll refer you to MoveMetrics Mobile Rehab Clinic.
How often will I train?
The 6-Week Program includes one private session per week. Additional app workouts and optional in-studio sessions can support faster progress if appropriate.
