Hi folks, this is my first post so please be nice!

I have a question about HIT and other exercise.

I’m early 30s, fairly overweight and very unfit, although I do go to karate classes 2-3 times a week (usually twice per week) which I’ve been attending for nearly a year. They’re hour long classes, and I get very puffed out and sweaty (especially during the warm-up, hah!).

I would like to start HIT to improve my fitness but I’m mindful of needing these ‘rest days’. So I guess I’m just wondering – if I go to karate on Tuesdays and Thursdays – what days I should do my HIT training? On karate days, the day before, the day after…?

Thanks!
Duckling.
