Sorry to hear that. I am afraid it has been 20 years since we did learn to skate so I really can't remember at what point if any this was introduced. Figure skating doesn't really and any two footed jumps in it, though it is probably not a bad exercise IF THE PERSON IS READY. It may be that most of your class are kids (I assume you're an adult) and kids being made of rubber it is possibly appropriate for them. It doesn't sound appropriate for adults, at least not for all. Better to start with a jumping preparation without taking off to get use to the knee bend and push, but start off slow and gradually increase the force and range of motion. One of the things you learn when learning to skate is what your limits are. You need to gently push past your comfort zone but unless you are happy falling often and have strong bones then if your body is refusing to do something then there's a reason and your teacher needs to find am easier progression for you. Even now in group lessons I find myself drifting off after one or two skills and just working on those for the rest of the lesson. There are of course 1-1s which are obviously more expensive, but can be combined with group lessons, but I think it's reasonable to say to the teacher "sorry I don't feel ready to do exactly this, yet, can you suggest something that moves my skills along in this direction that feels less uncomfortable".
