Or browse the internet between sets. It’s big brain time. I’m not even joking, if you’re going to waste time at least multitask and get stronger/healthier in the process.
This is the sole reason I use reddit on my phone. I keep a tab for AskReddit, open something for later if the title seems interesting enough, and at least skim the thread within a few days. No app, no login, old-style UI.
Since my brain is usually disengaged when lifting (gotta save those calories for what matters), I rarely bother with anything 'deep' between sets.
One potential upside of this is that the threads are usually a few hours or days old before I actually read them, which means that I can expect no new content from them once I have my fill of a thread.
