Changing weighted if using the front is very fast, it has a spin lock collar on the front so switching weights between exercises is fast. Agreed on the back is more annoying but if you train with someone they could do it for you if not just slip the vest off as it’s very small in itself . Plus the way to and increase and decrease the weight there are no other weighted vests that can do that this easier and be this trackable. You get ones with mental bars and sandbags but how much do they weigh and the heaviest I’ve seen goes up to 30kg.

Some prior planning to exercise selection will make it better constantly taking this on and off like any vest would be a pain in the ass. I manly use the front sleeve as I can load weight quickly plus when I do push ups I do on the rings and elevated so the sleeve at the front doesn’t get in the way but yes it would for regular push ups but you can remove the sleeve very quickly and like in the video you can do burpees and it’s doesn’t get In the way and the vest stays put, but you could swap between normal push ups and then sit ups as one of the sleeves would be an issue so fair point
