I push pull every bow I have. Recurves over about 50 to 55 pounds get a little tricky butunder 50 pounds are a piece of cake.
I will add that from personal experience, the most dangerous aspect of this method is the possibility of not getting the string loop securely set in BOTH sides of BOTH limb nocks. Longbows it's not too bad but recurves will twist and unstring rather violently at times. I've had one do exactly that. It was a 46#, 1957 bear Kodiak Special just like the Little Delta bow. I got the string securely in the upper limb nocks but evidently while bending the bow during the stringing process the string came partly out of BOTTOM limb nocks. I strung the bow and had just lifted it away from my foot when BAM! It felt like someone punched me. Took me a second to figure out what had happened and by that time there was some blood dripping off my chin. The upper limb tip had hit me square in the chin. I swear I could have given Curt Douglas a run for his money when it comes to a dimple in the chin. Of course, a couple minutes later it was no longer an "inny" but had swelled into an impressive "outy". Also, it happens SOOOO fast. There is absolutely no way to see it coming. Just BAM and it's all over.
Probably some of you are thinking "And you still string a bow that way? Are you crazy or stupid?" Neither atually. Just matter of fact enough about life in general to have learned a lesson on HOW to do something without being scared into NOT doing it ever again. I always check the lower loop first and I turn my head away during the stringing process. Then, before I release control of the bow limb I turn the bow sideways to get out of the line of fire if it were to "go off". It can be done safely but you have to do it right and think about what you are doing or you could be looking at a perforated face.
We carry sharp pointy sticks over rough ground with nothing between them and us but some leather (they are disigned to cut through hide to so what does that tell ya?) We climb up and down trees in the dark and do all manner of risky acts during a season. Stringing a bow isnt' gonna be something to scare me. I'm honestly more scared of relying of a bow stringer as I've had one of them slip off twice. I've also had great difficulty being able to slide the rubber block up the limb during the stringing process. If it comes down to trusting my bare hands or trusting a little bitty pocket tip holder and a piece of string, I'll trust my hands and experience.
