The Red Bull and Volvic seemed particularly out of place to me, especially in that he made buying them one at a time a part of his daily ritual. Maybe he wakes up in the morning with a compulsion to throw his money away at a 7/11 instead of getting a 12-pack from the grocery store? Instead of filling his own bottle from the tap and drinking coffee for his caffeine like normal people who don't attach brands to all of their routines?
I don't know the exact price of Red Bull or Volvic, but at $5 a day and 260 weekdays in a year he'd be spending $1,300/year.
Red Bull is $40 for 24 cans on Amazon, probably twice that at 7-11. Call it $3.20/can.
Volvic is $28.81/12 on Amazon. At the same 100% mark-up, it's $4.80/bottle at 7-11.
That's $8/day, plus local sales taxes, or nearly $2100/year.
Getting a good water bottle and filling it at home is likely too cheap to meter. Making good coffee at home and using that for the caffeine boost is a lot less than $3.20/serving, and then there is this:
The results of a study showed that the ingestion of one, 250mL can of sugar-free Red Bull, in a sample of 30 healthy young adults, had an immediate detrimental effect on both endothelial function, and normal blood coagulation. This temporarily raised the cardiovascular risk in these individuals to a level comparable to that of an individual with established coronary artery disease.
Finally, he jumps straight into 12 reps dumbbell press @ 30kg (66lb per hand). Riiiight!
I looked into energy drink costs compared to amazon and 7-11 and the difference is minor. Sometimes 7-11 is cheaper than amazon. Energy drinks are surprisingly price controlled.
I can't read the article you linked, but what would be the difference between drinking a 8.4oz red bull (~70mg caffeine) and drinking 1 espresso shot of coffee (~65mg caffeine) with a B-complex and taurine pills?
That really isn't that much weight- imagine bench pressing 60 kilos.
A more general rule is Bench Press = 3 x 1 dumbbell weight. Pressing dumbbells is harder because it involves more balancing, so it is harder to press 30kg dumbbells than one 60 kg bar.
You really don't need to warm up by actively doing something. Just like salivating your breathing and hart rate can increase in preparation for strenuous activity's.
On the one hand: yes, I hate brand manipulation too.
On the other: you have to triage. If you want to establish a morning routines like this, then you can't worry about every optimization or you will never get anywhere. I'm impressed as hell at his consistency.
When the price differential between 7-11 and Costco becomes the biggest problem in his life, and when he has plenty of time and space to screw around with inventory management, he can surely come up with a plan to fix that. Until then, 7-11 is solving the stocking problem for him.
