Even though I've recovered from that injury, I've kept the same pumping method. It just turned out to be much more ergonomically efficient than pushing the pump, using the weaker triceps, shoulder and chest muscles. (Although I do a lot of pushups, it's still easier to use the naturally stronger biceps.) At 5'11", 150 lbs, I'm no bodybuilder. Not quite skeletal, but I'm not winning any arm wrestling contests. Even when I tried to build upper body muscle it never developed.
It helps to use an efficient pump. I mention the Topeak RaceRockets a lot because they work really well. Remarkably easy to pump considering the size, with good ergonomics -- rubber grip, rounded end caps. I have both the shorter HP and longer HPX, and both are very good -- outstanding values. The Blackburn Core Slim is just as good in terms of stroke effort and efficiency, but less ergonomically friendly, with no rubbery grip and hard metal edged end caps. I wrap a glove or bandanna around the end cap. Very little volume per stroke, so it takes 200-300 strokes to pump to riding pressure, around 60-90 psi. But each stroke is manageable.
In contrast I have a "Pro Bike Tools" mini-pump that resembles a Lezyne, with detachable hose and built in gauge. It looks really well designed and made. But it's very difficult to use, requiring much more effort per pump than the Topeak. I can't get any tire properly inflated with that pump, which is convertible between Presta and Schrader (I thought maybe it'd be better with higher volume, lower pressure tires but it's not great on my errand bike hybrid either). I'd be disappointed if I'd paid for that pump, but I found it along the roadside. I'll probably give it away -- probably to a bigger guy with big guns, preferably someone I don't really like.

I also carry a pump on each bike. My minimalist approach is a single, small top tube bag and a single under seat Topeak wedge bag with tools and two different tube types. I have a Topeak bag mount on each bike and just slide on/off which ever bike I choose to ride that day. I have a similar bar mount for each bike and a Topeak bag that carries a small camera or perhaps a rain jacket.. though I avoid rain like the plague.

I always carry two CO2 cartridges and aRoad Morph pump, but in this heat, I would always use the CO2. Disadvantage of CO2 is that your tire will be slightly soft next morning because CO2 diffusion through the rubber is higher than that of air, which is mostly nitrogen.

Both
Like many others, I carry both; basic CO2 inflator and Lezyne Road Drive - https://ride.lezyne.com/collections/...-mp-rddr-v2l04). Started this when I got a second flat on a solo ride and only had 1 CO2 cartridge. I like this pump because it's small, has an easy to use hose, and actually does a good jump.
I'll sometimes use the pump (Lezyne Road Drive - https://ride.lezyne.com/collections/...-mp-rddr-v2l04) to find the hole in the tube if there's nothing obvious in the tire. But C02 is always the first option - I'm a cyclist, not a body builder!!

Pump. And nothing but.
My first flat after buying a CO2 inflator was the last. Got the new tubular up to about 80lbs before it was spent .. not enough to ride without damaging the rims so I had to call someone to pick me up.
Guess if I carried 4 or 5 CO2 cartridges it would have been different, but the reason I went that route was to reduce the amount of stuff I need to carry.
A good pump wins every time.

I carry both. A small Topeak or a Lezyne, with screw-on hoses plus a CO2 pump and 2 cartridges. Having had front and rear punctures in quick succession, I also carry 2 spare tubes. Oh and Lezyne quick patches too.

I carry both, various frame or mini pumps and a couple of different inflators. On the road, I will pump up the tire and top it off with an CO2

I used to carry a pump. Then I had a long stretch of almost a flat every few days. Finally I just got Gatorskin tires. They are considerably draggier but I haven't had a flat on my roadie since.
Prior to that I found a spare tube was the only thing that helped, patches being a crap shoot, frustrating, so my pump was my choice. I don't do long drives, just one hour drives.

Pretty much the same here.
Gatorskins. They substantially cut down on flats but they have more drag, but better than flats all the time. I carry a Road Morph pump.

I carry both. I have a inflator and two cartridges in my saddlebag and a mini-pump in my jersey pocket. If I was to carry just an inflator I'd pack an additional cartridge.

Oh JHC, unless you are in a race, PUMP.
- No waste from those steel cylinders.
- Pump is plenty fast on a bike tire, especially a road bike with skinny tires, but even a mountain bike.
- Air is free.
- You can help out someone else with a flat without depleting your cylinder supply.
- You can use the pump to find a small hole in the tube before patching.

Hills!
After today, I think I'll find my Road Morph and put it on my road bike. Had a pinch flat today and while using the CO2 to inflate, the head of the inflator blew off not to be found anywhere and all the CO2 went to atmosphere. So my spare CO2 cart was rendered useless. Fortunately a kind motorist brought me his bicycle hand pump which got me going again.

I carry two CO2 cartridges. I can inflate a tire to over 100 psi in about 10 seconds. Last time I used a hand pump, it took 5 minutes of tedious pumping and still couldn't get the tire any near 100.

I carry 1 co2 + 1 lezyne pocket drive (which weight about the same as a co2 cartridge). It's just nice to get going again ASAP, and to also have that shot of air to make sure the tire hooks back up again on my gravel bike if the bead broke. If things get worse, I'd still like to hobble home no matter how long it takes using the micro pump, tubes and patches if things are just terrible.

That's great having a 2nd CO2 cart until the inflator hard fails. See my post just above.

I've owned the Portland Design Works inflator head for over six years and its performed perfectly every time. I could carry an extra head - they're so small but then again, nahhh. Before, when I used to carry only one cart, I had a second flat and had to borrow a pump and pump and pump and pump and pump....I learned my lesson!
