Is it really necessary to stay away from intense exercise for 1 month after PDO thread lift?

I had PDO threads inserted for lifting nasiolabial folds 1 wk ago and am pretty satisfied w/results but they told me to stay away from any high-impact exercise such as jumping and runnning for 1 month following to avoid the threads from snapping. Is this really necessary? The only exercises they told me I could do are stationary bike and elliptical. I'm used to exercising intensely and am noticing in just one week how my body misses the activity.
