I'd say do some weight training and the Yoga.
Weight training will impatc on the heart of cours,e but as long as you were'nt lifting weights all the time ot the point where your Arms nearly collapsed, thne you'd be okay.
Just make sure not to use exercises that might increase injury risk to things like the Shoulder are, or Wrists in particular, use good technique and don't overload on the weight and do too much.
The Yoga would be a good supplemental thing, so Weights 3 times a week, Yoga 2x. Potentially like this.
Day 1. Weights
Day 2. Yoga
Day 3. Weights
Day 4. Day off
Day 5. Yoga
Day 6. Weights
Day 7. Day off.
Maybe that would be viable.
I'd alos increase calories as they're a bit low at times. Sedentary females need around 1,800 a day, so I'd aim for 2,100-2,200, so you've got some to use for exercises and also to make sure you're getting a little bit more quality nutrition, to help your musculoskeletal system and organs develop a little more wellness and good condition.
