Frequently asked questions

Everything you need to know before you lock in.

When does the May Locked In Challenge start?
May 3, 2026. The challenge runs for 4 weeks (closes May 30). Open the SGS app on day one and tap Join Challenge on your home tab.
How do the mystery prizes work?
Up to £1,000 in mystery prizes drawn across the 4 weeks. Show up, log your sessions in-app, and you're entered. Weekly draws plus a bigger completion draw at the end. Specifics revealed inside the app.
I'm a total beginner. Is this for me?
Yes. SGS is built for women who've never seen themselves as runners or lifters. Every workout has beginner modifications and there's no streak shame if you miss a day. Real coaches in your corner, not an algorithm shouting at you.

No. The challenge mixes running, strength, Pilates and HYROX-style work, with most workouts having a home or equipment-free option. Train wherever suits you.
I'm already an SGS subscriber. What do I do?
Just open the app on May 3. The challenge appears on your home tab. Tap Join Challenge and you're in. No re-subscribing, no extra fee.
What if I miss a day?
Catch up at your own pace. There's no streak penalty. Workouts unlock weekly so you've got room to flex around real life.
Is the challenge included or extra?
Included free with every SGS plan. There's nothing extra to buy. Locked In is one of many things in the app: workouts, recipes, journal, community, watch sync.
Can I cancel after the challenge?
