Monica Puig on Wearables: Embrace the Data, Let Teams Manage the Noise
Monica Puig says players should accept wearable data while letting teams manage the details. Indeed.
Monica Puig has approached performance from many angles: an Olympic gold medalist who built her game on relentless athleticism and “Pica Power,” a player who retired in 2022 and then turned to marathons, triathlons and IRONMAN events. Now an analyst and self-described tech enthusiast, she has tested WHOOP, Garmin and COROS while training and recovering.
“I’ve tried it all!”
Her experience with continuous tracking shaped how she used the information. “I did wear the WHOOP for a while, but that was back before you could wear it on a match court. I know there’s been some back and forth about whether you can at certain tournaments.
I would wear the WHOOP, but I wouldn’t take the information for myself. My fitness trainer was the one who had the app on his phone and had my WHOOP paired to his phone…” Puig said she handed data to the people charged with her body care to avoid letting numbers skew her mindset.
“It’s a fine line. If you’re really responsible with the information that you receive you can kind of just treat it as it is, which is a number…
If you’re the type of player who gets a little bit too obsessed with the numbers, hand it off to your team, like I did, and have them kind of make the adjustments. Let someone else take care of it, then you just kind of go along for the ride.
Because the numbers are very good for certain things, but there are also metrics that don’t really help you.”
On the measures she found most valuable, Puig emphasized recovery and early illness detection. “Knowing your fatigue levels… I thought WHOOP was really great with this knowing when you’re getting sick. And showing you how the body reacts differently, whether you drink or not, whether you hydrated enough, whether you had a heavy meal or not—all those things can play a part into your recovery.”
She supports allowing devices in matches so teams can analyze how an athlete responds under pressure. “Absolutely. I think it’s really essential, because you can also see the way that your body handles itself in a pressure situation. Your body reacts differently from a match that you win in an hours, versus a match that could go for three hours. And obviously it reacts differently in a match than in practice.
There are so many different factors, and I think nowadays having the information helps you prepare. There’s no reason why it should be concealed from players.
It’s not like the player is looking at that information when they’re playing. It’s not like your coach is going to be saying, ‘Oh my gosh your heart rate is X! You need to get it down to Y!’”
She added that showing biometric data in competition has precedent. “I would love that, and I think the WTA did do that when WHOOP was first a partner (back in 2021).
I’ve seen it in golf a couple of times, where it would show a golfer’s heart rate before they teed off. Then you would be like, OK the heart rate is maybe at 130. They’re feeling the stress. Or if the heart rate was in the 90s, OK they’re feeling alright.”

Auger-Aliassime Records 100th Week Inside ATP Top 10
Auger-Aliassime reaches his 100th week in the ATP Top 10; he is currently ranked No. 5. Milos Raonic
Felix Auger-Aliassime is celebrating his 100th career week inside the ATP Top 10 as the clay-court major approaches. The Canadian has reached the milestone in four separate stints: November 15th to 21st, 2001 (one week), January 10th to September 11th, 2022 (35 weeks), October 17th, 2022 to June 11th, 2023 (34 weeks) and October 27th, 2025 to present (30 weeks and counting).
Auger-Aliassime is currently at his career-high ranking of No. 5 and joins a small group of players born in the 2000s to accumulate triple-digit weeks in the elite. The draft notes he reached the mark “after exactly who you’re thinking.”
The milestone places him among the longest-serving Canadians to reach the Top 10. He becomes the second Canadian to log that many weeks at the top of the rankings, following Milos Raonic, who spent 151 weeks in the Top 10 across the 2013, 2014, 2015, 2016 and 2017 seasons. Denis Shapovalov is the only other Canadian to have reached the ATP Top 10, spending 10 weeks there across 2020 and 2021.
The pattern of Auger-Aliassime’s tenure in the Top 10—multiple returns to the group rather than a single continuous stretch—highlights his resilience and consistency at the highest level. As Roland Garros nears, the 100-week marker is a reminder of his standing on the ATP Tour and of the depth of Canadian men’s tennis in this period.
