Joinform Review 2026: Is FORM's Workout Membership and Matching Activewear Worth It?
6:40 a.m. The coffee is brewing, the yoga mat is already unrolled on the living-room floor, and you have exactly thirty minutes before the day starts making demands. No commute to the gym, no guessing what to do — just a workout queued on your phone and a matching set that doesn't ride up when you roll into the next move. That's the little routine FORM, the brand behind joinform.com, is built around.
FORM is two things at once: an on-demand workout membership and an activewear line designed to wear while you use it. SweatproofGear went through both in October 2026 — the membership details, the fabrics, the prices and the return rules — so you know what you're paying for.
The Story: Two Samis and a 30-Minute Idea
FORM's About page introduces two co-founders. Sami Clarke started her career in modeling before moving into training; the brand says she holds certifications in Mat Pilates and ISSA Fitness and built a following through in-person sessions and YouTube workouts. After "discovering the power of 30-minute workouts," she set out to give busy women the tools and motivation to keep showing up. Co-founder Sami Spalter is described as the brand's "biggest believer." The two also host Transform, a podcast about showing up and staying consistent.
The store lists Oceanside, California as its home, and the company describes FORM as "your digital platform for all things fitness, wellness, and self-love."
What Makes FORM Different
- A membership plus a wardrobe. You can subscribe to the workouts, shop the activewear, or both — and members get first access to new activewear drops, according to the membership listing.
- 1,200+ on-demand workouts across Pilates, strength, HIIT, weights and gym-based sessions, with new classes every week (per the brand).
- Done-for-you weekly schedules, so you open the app and follow the day's plan instead of scrolling.
- Short or long sessions. The brand mentions 10-minute flows you can stack and longer gym workouts; class lengths on the homepage run from 5 to 60 minutes.
- One fabric family. The leggings, shorts and bras we looked at all list 75% polyester / 25% spandex, so pieces mix and match.

The Lineup: Membership and Gear
| Product | Price | Who it suits |
|---|---|---|
| Free trial | 7 days | Anyone curious about the classes |
| Monthly Membership | $22 for the first 37 days, then $28/month | Commitment-shy beginners (cancel anytime, per the brand) |
| Annual Membership | $138.99 for the first year plus a bonus week | Regulars who'd use it all year |
| Core Shorts 5" | $74 | Pilates and warm-weather sessions |
| Core Leggings | $88 | Everyday training, XS–XXXL |
| Layered Bra | $72 | Higher-support needs (cups A–G) |
| Knot Bra | $72 | Low-impact days (low support, cups AA–C) |
| Track Legging | $92 | A low-rise, straight-leg look (34" inseam) |
| FORM Grip Socks | $20 | Pilates and barre-style classes |

Monthly or annual?
The membership listings make the math clear: the annual plan at $138.99 works out to about $12 a month, and FORM says it saves "over $190" compared with paying monthly. If you're not sure you'll stick with it, take the 7-day free trial first, then decide.
Which bra?
Match the bra to the session. The Layered Bra lists high support and high coverage for cup sizes A–G. The Reversible V-Neck is medium support with two colorways in one. The Knot Bra is low support and designed for cups AA–C — better for Pilates and stretching than for jumping.

FORM FAQ
What is Joinform?
Joinform.com is the home of FORM, a digital fitness platform with on-demand workouts, weekly schedules, recipes and guided meditations, plus an activewear shop.
Do I need gym equipment?
No. The brand recommends a booty band, 3–15 lb dumbbells and ankle weights, but says there are plenty of equipment-free workouts.

No. FORM doesn't accept returns or exchanges on sale items, and Last Chance purchases are final.
Our Verdict
FORM is a smart package for people who'd rather follow a plan than invent one: a big on-demand class library, weekly schedules and an activewear line that matches the vibe. The membership pricing is friendly, especially annually; the gear is premium-priced, ships free only over $250 and is strict about sale returns. Take the free trial, grab a set when there's a markdown, and check our FORM deals page before you order.
