Hi Mathilda, listen your body and talk about your goals with an expert in the sector in your gym , which follow you. It's not so easy to programme a training with different activities (karate- weight training). I trained for many years with weights and kick boxing and i know what you say,
The key,for my point of view, is to be followed from competent pro, because each person is different and needs of different advises.
cheers
