Challenge

Rebuild the platform from the ground up

Complex technical features undermined smoothness. Lack of a design system and brand image infringed on UI.

As the lead designer, I aimed to bridge the gap between Michael's product vision and the user's full experience on the platform.

Key Opportunities

Enable scalability

Ensure that this product can support an expanding library of workout types in the future (e.g. ballet).

Context

Boxing as a (personalized) science

When Michael Olajide, a former pro boxer, launched System of Silk, he envisioned an online platform where users could build personalized workout playlists and experience boxing as a science.

Solution

Prioritizing a Mobile-First Handoff

Market research showed users primarily use their mobile devices when working out. Most competitors didn't even have desktop versions. So I framed my design process around creating a familiar mobile experience.

Browse page on mobile

I made browsing smoother.

With a variety of content to choose from, organization was a priority. Filter chips reduce cognitive load while increasing the speed of decision-making and scalability.

I organized the content.

With two distinct ways to browse content, tabs offered a clear and scalable navigation pattern. Because each tab houses the same content architecture, they help distinguish these experiences in a logical way.

Adding a workout to a custom playlist.

I familiarized customization.

Considering Jakob’s Law of familiarity, it would benefit all stakeholders to leverage existing mental models. Inspired by YouTube and Spotify's seamless playlist building, I used bookmark icons and interactive modals to make the process simple and intuitive.

I made playlists more visible.

Our engineers found that utilizing Vimeo as API was cost-efficient and client-friendly (as opposed to using CMS). This enabled us to design interactive playlist pages that store data reflect content changes.

Customizing playlists is easy.

Browse page on mobile

I made it easier to watch.

Of all video platforms that were considered, 100% had clear indicators of visibility of system status. Users must always be informed about what is going on, and this design gives them control.

Responsive Redesign

Designing an all-around experience

As shown in Product, bringing System of Silk to mobile was essential to making the product accessible. Translating the native-app feeling of the new site continued through desktop and tablet.

Iterate, iterate, iterate

Maybe starting with the marketing site wasn't the best approach…

Looking back, tackling the marketing site last would have been smoother, having known the exact features and functionalities to highlight.

Originally, users were presented this tutorial pop-up after every log in. It wastes about 30 seconds on the first log-in, and then about 5 seconds every time after.

Original tutorial (pop up) users would see after every log in.

Redesign of The Workout page (marketing site) includes tutorial section.

Designing the product tutorial into the marketing site not only removes an unnecessary step after log-in, but it reduces support tickets and enables users to preview the product before purchasing.

Building a Design System

Without an existing design system, I learned to build, develop, and iterate on components as the product evolved.
