Workout routine (Crossfit, aerial arts, ...)?

So last year I lost about 19 kg of body fat eating healthy and doing Crossfit about 5 times a week for 3 months. After a year abroad (and loads of crappy food), I gained most of it back and have recently started working out again. I've taken up aerial arts (pole fitness, aerial hoops and silks) because I wanted to learn to lift myself up and gain more confidence in what my body can do on its own. However, I'm not sure if the results (in terms of body shape) will be comparable to those of Crossfit. Based on other people's experience, weightlifting helps a lot with saggy skin, which I hugely struggle with and makes me feel terrible while on the pole. So my question is do you think aerial arts help with saggy skin and overall body toning? I try to train aerial arts 4-5 days a week and Crossfit once or twice a week. What do you think of this hybrid? Should I increase my Crossfit workouts?
