MORE RESISTANCE MORE POWER

Harness Strongside: +52KG Power and Speed

🧬 Innovation: Under-Axillary Guidance

The secret of STRONGSIDE lies in the resistance path. The bands are anchored to the spine and pass precisely under the armpits.

Why is it vital? This placement ensures that resistance is 100% opposed to your punches. Unlike systems that pull on the shoulders, here the force vector is pure. You protect your joints while maximizing explosiveness.

DAILY USE

THE REALITY

BACK ELASTIC

Chafing under arms, back, shoulders... and constant slipping. You spend more time adjusting it than punching.

DUMBBELLS

They pull downwards (gravity). You destroy your joints and lose your snappy speed.

FIXED ANCHOR

You are "chained" to a pole or wall. No pivoting, no movement. Fighting is movement, not static.

HANDLES OBSTACLE

Impossible to wear gloves. You lose the fist clench and real fight sensations.

STRONGSIDE PRO: BOX WITHOUT CHAINS

Tired of training held back by obsolete gear? The Strongside Pro Boxing Harness is the revolution demanding fighters have been waiting for. Designed for those who refuse compromise, this harness transforms every shadow, bag, or sparring session into a pure, ultra-realistic resistance experience.

Total Freedom of Movement

Forget the wall anchor. Our 360° mobile anchor system follows your pivots, slips, and movement without ever slowing you down.

Striking Technique Preserved

Unlike dumbbells that pull down, Strongside offers horizontal resistance aligned with your punch axis. You gain power without distorting your "snap".

Comfort & Performance

A harness that doesn't slip or burn. Progressive tension that respects your anatomy and protects your joints.

Compatible with Your Gloves

Don't sacrifice your feel. Our ergonomic design frees your hands: put on your usual combat gloves and work your real guard.

"Don't be a slave to a pole anymore. Take your ring everywhere."
