Sadly, an older gentleman at church is at that point. He says the push mower is hard to start and he just can't pull it over fast enough. It is tough on an ex marine and farmer to realize you can't do things.
Get him to try a thinner base oil multigrade oil , makes a big difference
A very short customer showed me the trick of pulling the rope while pushing the handle.
That works well for a lot of women & was what I had to do for 18 months after the RA gone & I was left very weak.
The long rope through an eye 2/3 up the handle ( don't know if it is a thing in the USA ) also helps a lot , particularly if using the handle push method of starting.
After that is is a Honda powered mower as Hondas do start a lot easier
Down here I get them to try one of my Victas with a new decompressor because those are all about speed and not effort .
