Boost Go

No more guessing. Every session has a real plan behind it.

R299/month

About R10 a day

  • Gym: 3 sessions a week (4 on Fat Loss). Home: 3 sessions a week
  • In the gym: 4 programs (Strength Gain, Muscle Building, Fat Loss or Hybrid), matched to your goal, and you can switch later
  • At home: one full home program built around the equipment you've got (or none), with a training focus for your goal
  • A weekly meal plan generated for your calories: individual foods with real quantities, not vague recipes
▸Read more
  • At home, 3 difficulty levels (Modified, Standard, Advanced), starting from your experience
  • A new training focus every month, with technique progression
  • Couch to 5K/10K running program built in
  • Full food logging against a food database for anything else you eat
  • A month end progress report

Most people who already train aren't looking for motivation, they're looking for direction. Tell us the goal that's actually yours and where you train, gym or home, and you get a real program built around it, not a guess.

The missing piece nobody else is fixing for you.

R199/month

About R7 a day

  • Real calorie and macro targets, calculated from your stats and goals

  • Monthly check ins that recalculate your targets as your weight and goals change
  • Works alongside any training you're already doing

You've already got the training side handled: a gym membership, a sport, a routine that works. What's actually holding you back is quieter than that, never really knowing if you're eating enough, or eating right, for what you're trying to do.

One-on-one coaching with David, monthly or weekly.

Boost Coach

This is what it feels like to have someone in your corner.

R950/month

About R31 a day

  • A personalised training programme, built around your goals and experience: full gym, full bodyweight at home, or home plus whatever equipment you've got, your call
  • A full nutrition plan, built specifically for you
  • Message David directly in the app, whenever something comes up
▸Read more
  • Exercise swaps for a real alternative, no guessing
  • A Progress Tracker and progress photos, so change is visible, not just felt
  • David reviews your actual results every month, and rebuilds your program around it
  • Handles situations templates can't: injuries, specific sports, competition prep, real life getting in the way

An app can log your sets, but it can't notice that your progress has stalled for three weeks, or that new knee pain started the same week you added lunges, and connect the two. David does, because he actually reads your history and keeps real notes on you, not just your last workout.

  • Ideal for anyone chasing a real deadline: a competition, an event, or a goal with a date

A month is a long time to keep training through something that isn't working. Coach+ closes that gap: the same hands on coaching as Boost Coach, checked and adjusted weekly instead of monthly, so nothing slips through for four weeks before anyone notices.

Questions

Can I cancel any time?

Yes. Cancel in the app under Manage billing. Nothing more is charged, and you keep your plan until the end of the time you've paid for, or the end of your free days.

What if it's not for me?

Cancel within 7 days of your first payment and we refund it in full. Cancel in the app under Manage billing.

Do I need a gym?

No. Boost Go has a full home program built around the equipment you've got, or none. Boost Coach can be full gym, full bodyweight at home, or home plus your equipment. Nutrition Only works alongside whatever training you already do.

Can I eat foods I like?

Yes. When you sign up you tell us your diet (for example vegetarian or halal), foods you like and foods you don't. Your meal plan leaves out what you don't eat and builds in foods you like, and you can log anything else you eat against our food database.

Who's behind Boost?

David Thornhill, owner of Boost Fitness Gym in Cape Town. He built this app, and on Boost Coach and Coach+ you work with him directly.
