After a sit-down interview with Apple CEO Tim Cook for "Axios on HBO," Axios got a tour inside the exercise lab Apple uses to make sure its watch can accurately track your workout of choice — whatever that might be.

Details: Parts of the lab resemble a gym, with dozens of treadmills, rowing machines and other exercise machines. There's also a yoga room and an endless pool, which allows Apple to better track how people are swimming — as different strokes burn different amount of calories.

What makes Apple's lab quite different from any gym are the bulky masks you see on each of the people working out. Known as a metabolic cart, the machines precisely determine just how many calories are being burned in each activity.

Then there are the 3 temperature-adjustable rooms (dubbed Higher, Faster and Stronger) that can be made extremely hot or very cold.

"We have done over 50,000 sessions of data collection which is almost 100,000 hours of data being collected. That includes over 12,000 unique participants so it’s a very diverse set of data as well which is really important because obviously, everyone’s body is different and we want to understand as much as we can about different types of people."
— Apple's fitness director Jay Blahnik

The bottom line: That adds up to a huge bet on health and fitness. The Apple Watch available today is just the beginning.

Sen. Mitt Romney (R-Utah) on Saturday tweeted a scathing response to President Trump's Friday night commutation of former associate Roger Stone's prison sentence, calling the move "[u]nprecedented, historic corruption."

Why it matters: Romney has emerged as the party's most prominent Trump critic. He sent shockwaves through Washington after announcing he would vote to convict Trump in the impeachment trial — becoming the only Senate Republican to break ranks and vote for the president's removal from office. Now he is the first major GOP lawmaker to condemn Trump's Friday night call regarding Stone.

We're losing the war on the coronavirus

Chart: Danielle Alberti/Axios

By any standard, no matter how you look at it, the U.S. is losing its war against the coronavirus.

Why it matters: The pandemic is not an abstraction, and it is not something that’s simmering in the background. It is an ongoing emergency ravaging nearly the entire country, with a loss of life equivalent to a Sept. 11 every three days — for four months and counting.
