Training, health and camps

Two sessions a day, most weeks of the year. What that looks like day to day, and the camps she is putting together to teach it.

Training & recovery

Pads, sparring and ring work in the morning, strength and conditioning later. Sleep and physio count as training.

Food and weight

Strawweight, 52 kg. Steady habits through camp instead of a crash week before the scales.

Camps

Thailand, Poland and Sweden. Small groups, her own coaches, all levels welcome.

Inside a training week

“The hard part isn't fight night. It's the Tuesday morning session nobody would notice if I skipped.”

Background

It started in Thailand

She was eight, on holiday with her family, when she watched a girl her own age fight. She went home to Stockholm and asked for gloves. Twelve years later she trains at the same gym in Khao Lak, and the girl she watched is a world champion and a friend.
