An estimated 80% of Americans engaged in some type of sports or fitness activity within the past year, a record high, according to a 2025 report. This year’s fitness landscape is shaped by various influences ranging from social media trends to time-tested military practices, along with some innovative equipment. However, experts advise that not all trends deliver the same results.
Here’s a look at five significant fitness trends emerging in 2025, along with insights from fitness trainers regarding each method.
No. 1: The 12-3-30 Treadmill Trend
The 12-3-30 routine—walking for 30 minutes at a 3 mph pace on a 12% incline—gained popularity on TikTok and is now supported by research. A recent study suggests that it burns as many calories as self-paced running. While running typically burns more calories per minute, the walking approach utilizes a higher percentage of fat for energy.
Mary Wells Sutton, a certified trainer at Crunch Fitness in New York, shared that it’s not surprising to see running burn calories more rapidly. She explained that the 12-3-30 method is indeed more demanding than walking flat but less intense than running.
Part 2: The Rise of Weighted Vests
Weighted vests, once a staple in military training, have resurfaced as a trendy fitness tool, especially highlighted by social media platforms. With the hashtag #weightedvest on TikTok racking up over 30 million views, the vests are making a significant comeback.
Dr. Mark Kovacs, a sports scientist, noted this resurgence is driven by social media’s influence, though they’ve been utilized in sports training for ages. These vests can intensify regular walks without changing the method itself.
Research indicates that wearing a weighted vest can boost calorie burn and cardiovascular effort, although long-term outcomes may vary. Kovacs emphasized the importance of maintaining good posture and gradually increasing weight while always listening to one’s body to avoid injury.
3rd Place: Family Fitness and Jiu-Jitsu
With well-known figures like Ivanka Trump and Gisele Bundchen embracing it, Jiu-Jitsu is receiving renewed recognition, not just as a sport but as a necessary self-defense skill. The Valente brothers from Miami, who train the Trump family, describe Jiu-Jitsu as a comprehensive practice that offers physical, mental, and emotional benefits.
Joaquín Valente remarked on their inclusive approach, saying they start training children as young as three and continue with students into their late 80s. This adaptability makes it appealing for all ages.
Besides fitness, the trainers highlight Jiu-Jitsu’s role in fostering presence and emotional stability. Pedro Valente emphasized the significance of evading conflict, as being caught in a physical altercation puts one at a disadvantage.
Gui Valente added that Jiu-Jitsu engages all muscle groups differently, requiring endurance, flexibility, and mobility from practitioners.
Part 4: TikTok’s 50-Jump Morning Ritual
A quirky trend gaining traction involves jumping 50 times right after getting out of bed, credited to Kathryn Smith, who admits she’s not typically disciplined. In her TikTok video, she shares her struggle with laziness but frames this morning jump as a simple way to boost energy and circulation.
She believes this routine instantly elevates one’s mood, noting that increasing heart rate helps oxygenate the brain. Sports nutritionist Maura MacDonald comments that this easy routine is likely to stick around, given its simplicity compared to more intense workouts.
No. 5: Vibration Plates for “Easy” Training
Vibration plates, which provide whole-body vibration, are trending as a potential shortcut for gaining strength and reducing fat. They claim to improve flexibility, circulation, and bone density by engaging muscles through continuous contractions.
Experts caution, however, that reliance solely on these plates isn’t sufficient; they shouldn’t replace regular exercise and healthy eating habits. Nick Wilson, a trainer at F45 Training, observed that while vibration plates can aid muscle activation, they can’t replace conventional cardio or strength training routines. Some research shows they might assist in weight loss when combined with a calorie-restricted diet and can also alleviate issues like back pain and high blood pressure.
