Fitness Spark
Overview
Role: Solo Designer & Product Developer
Timeline: 3 months from concept to production
Platform: Physical card deck with 52 prompts
Status: Initial production run complete, gathering user feedback
The Insight
That morning, work felt particularly daunting. I felt a sudden compulsion to do something physical. After nine hard reps of barbell back squats the dread that had been weighing on my mind noticeably diminished.This spontaneous two-minute intervention sparked a question that would shape this project: How might we help people harness brief physical interventions to transform their daily experience?
The Challenge
Despite decades of fitness industry innovation, we've largely missed a crucial insight: exercise isn't just about getting stronger or healthier—it's a powerful tool for intentionally changing our mental state. The problem is threefold:
People view exercise only through the lens of fitness goals
The perceived barrier of long time commitments keeps people from starting
There's limited awareness of how specific movements can elicit specific mental states
As someone with five years of experience as a personal trainer, I'd seen countless people struggle with exercise adherence. But this insight suggested a completely different approach - what if instead of focusing on long-term habits, we could give people tools for immediate state change when they needed it most?
Design Approach
Rather than create another app in an already crowded digital wellness space, I chose to develop a physical card deck. This decision came from several key insights:
Why Cards?
Speed to Market: Faster path from concept to product compared to app development
Counter-Cultural Appeal: Offering an analog solution in an increasingly digital world
Tangibility: Physical product creates stronger perceived value and engagement
Low Barrier: No tech requirements, immediately usable anywhere
Conversation Starter: Physical format serves as a catalyst for broader wellness discussions
Two Paths to State Change
At the core of Fitness Spark is a crucial insight: meaningful state changes can come through both physical action and mental reflection. This dual approach emerged from understanding that different moments call for different interventions:
Physical Interventions
These prompts leverage the direct mind-body connection through movement. Like my original squat experience, they create immediate state changes through physical action. The key is specificity - each movement is chosen for its particular psychological effect.
Reflective Interventions
These prompts create state changes through guided mental focus. Take the "Self Steer" card:
Action: "Set a timer for 2 minutes and write a letter to your future self expressing concern about current habits and offering advice for staying healthy."
Principle: "By envisioning your future self and articulating your aspirations, you strengthen your commitment to well-being and inspire positive change."
This isn't just journaling - it's a focused mental intervention with a clear time boundary and specific prompt that plants seeds for future change.

Card Design: Intentional Minimalism
The anatomy of each card evolved through multiple iterations, challenging traditional exercise card formats. Here's why each element matters:
Action Prompt (Front) I deliberately broke from the typical exercise card format of showing step-by-step instructions with diagrams. Why? Because those create cognitive load - you have to process images, match your body to the positions, track multiple steps. Instead, I focused on simple, immediate actions that could be understood in seconds. The two-minute limit isn't just about time - it's about removing the "this will be too hard" barrier before it forms. When writing prompts, I found myself fighting the urge to be comprehensive. A trainer's instinct is to explain perfect form, give modifications, list benefits. But that creates the same overwhelm we're trying to avoid. Instead, I focused on what I call "minimum viable instruction" - just enough guidance to get someone moving safely.
Principle (Back) The back of the card was a controversial decision. Many early reviewers suggested putting multiple exercises or variations here. But that would've undermined the core goal: making state change accessible and immediate. Instead, I used this space to bridge the action-understanding gap. The principle explanation isn't just educational - it's permission-giving. When someone understands why a movement might help them, they're more likely to try it. The language intentionally avoids both scientific jargon and fluffy wellness-speak, finding a middle ground that respects users' intelligence while remaining approachable.

Playful Name (Both Sides) The naming convention was a direct response to how intimidating fitness can feel. Compare "Gratitude Giggle" to "Body Appreciation Exercise #4." One feels like an invitation to experiment, the other like a homework assignment. These names do triple duty:
Create memorability (important for reuse)
Lower psychological barriers through playfulness
Build a cohesive product personality
I specifically chose to repeat the name on both sides - a small detail that helps users quickly find specific cards they want to revisit without flipping through the whole deck.
Visual Design Decisions
The visual design emerged from both practical constraints and user needs:
Graphic-Free Design
Deliberately chose to exclude illustrations or diagrams
Benefits:
Forces focus on content and instructions
Reduces cognitive load during moments of low motivation
Significantly simplifies production as a solo designer
Creates clean, professional aesthetic
Avoids potential visual misinterpretation
