A 4 week challenge on the JEFF App.

Three coaches.
Three approaches.
One stronger you.

Joe, Meka and Nadine, the Triple Threat coaches

Four weeks to build real strength, better fitness and a habit that sticks.

Monday 14 September 2026 - Sunday 11 October 2026

Triple Threat is a 4 week strength, core and fitness challenge led by Joe, Meka and Nadine. Three sessions a  week, 40 minutes each, and every single one is full body.

R650 for JEFF members · R1250 once-off pass  

One challenge. Three coaches.

Most challenges give you one style of training for four weeks. This one gives you three. Each coach takes a day  of the week and brings something different, so by Friday you have trained your whole body three different  ways.

JOE BARRETO

MONDAY · Pure Strength

Joe brings the strength. Solid foundations, moving well, and lifting with confidence.

MEKA TUSSLER

WEDNESDAY · Strength & Fitness

Meka brings the fire. Strength and fitness blended together to get your heart pumping and your energy up.

NADINE SAMANTHA

FRIDAY · Low Impact & Core

Nadine brings the control. Low impact strength and core work that is kind to your body but still challenges you.

Every session is full body, so no matter which days you train, you are always giving your whole body what it  needs.

What four weeks will do for you

Four weeks is long enough to feel a real difference and short enough to stay committed. Here’s what you’ll walk away with.

You’ll get stronger, week on week

Every session builds on the last one. By week four you’ll be lifting heavier and moving better than you were on day one, and you’ll feel it.

You’ll build fitness that shows up in real life

Stairs, hills, chasing your kids, long days on your feet. Three sessions a week is enough to change how all of that feels.

You’ll build a stronger core and better control

More than abs. The deep stabilising muscles that improve your posture, protect your lower back and make every other movement easier.

You’ll build a habit that outlasts the challenge

Three sessions a week is realistic. By week four it stops being something you’re doing and starts being something you do.

You’ll feel more confident in your own body

Knowing how to lift properly, when to push and when to hold back, and knowing you finished what you started.

You don’t need to train every day or eat perfectly. You need to show up three times a week for four weeks. We’ll handle the rest.

Built for every level

Whether you are starting out, coming back after a break, or already training regularly, this works. Every session has modifications, so you can dial it up or down as you need on the day.

Train at home with a few dumbbells, or take it into the gym.

Nothing is live, so there is no class to be late for and nothing to miss.

Three sessions a week, not six. It is designed to fit around a real life.

Two WhatsApp groups and three coaches, so you are never doing it alone.

Questions

What equipment do I need?

Dumbbells in light, medium and heavy, a bench or a sturdy chair, resistance bands (fabric ones are best) and a yoga mat. Your eBook has a full guide on choosing weights and knowing when to go heavier or lighter.

I am a complete beginner. Is this for me?

Yes. Every session has modifications and your coaches talk you through them as you go. Nadine’s Friday sessions in particular are low impact, so there is always a gentler way in.

What if I miss a session?

Nothing is live, so nothing is missed. Every class sits on your planner page and stays there. Catch up whenever it suits you.

How do I access the classes?

In the JEFF app on your phone, on your laptop through the JEFF website, or airplayed to your TV. Triple Threat appears on your home screen automatically once you sign in.

Do I need to be a JEFF member?

No. The once-off pass includes full JEFF app access for the length of the challenge. If you are already a member, you pay the lower member price.

Can I do this if I am pregnant, postpartum or managing an injury?

Please check with your doctor or physio first. Once you have the go ahead, tell us in the community group and your coaches will point you to the right modifications.
