Kettlebell Craze: Fitness Trend or Injury Risk?
TikTok Challenge Sparks Debate Among Experts
A viral fitness trend involving 100 daily kettlebell swings is gaining traction online, promising sculpted physiques and pain relief. But health professionals caution that this intense regimen may be doing more harm than good, particularly for those new to exercise.
The Appeal of Daily Swings
Videos showcasing the challenge have exploded on TikTok, amassing millions of views. Users report benefits ranging from a flatter stomach to stronger glutes and reduced back pain. The simplicity of the exercise—a single movement repeated many times—is a key part of its appeal.

However, experts advise caution. While strength training is beneficial for all ages, performing 100 kettlebell swings daily could be a recipe for injury, especially without proper form or a gradual progression.
Understanding the Benefits of Kettlebell Training
Dr. Kim Way, an exercise physiologist at Deakin University, explains that kettlebell training can increase muscle mass, strengthening bones and potentially reducing fat. It may also alleviate back and neck discomfort. However, studies typically examine kettlebell exercises performed two to three times per week, not a daily routine.
Associate Professor Justin Keogh, an exercise scientist at Bond University, notes that the weight of the kettlebell is crucial. Heavier weights build strength and power, while higher repetitions with less rest improve endurance and cardiovascular health. Kettlebell swings uniquely engage both upper and lower body coordination, mimicking natural movements.
Potential Risks and Injury Concerns
According to Keogh, attempting too much too soon is a significant risk. The chance that your hamstrings, lower back, forearms, etc, are going to feel really tight the next three or four days … is pretty high, and then you might not want to do any exercise over those next couple of days.
This can lead to delayed onset muscle soreness, a common consequence of pushing muscles beyond their current capacity.
Way emphasizes that 100 swings daily is a substantial amount, particularly for beginners. What I see with trends like this is that you’re getting people excited about an exercise, which is great … but exposing people, especially if they haven’t had any exposure to an exercise, that’s just an injury waiting to happen because you haven’t had the time to allow your body to adapt to the muscle stress, and the joint stress, that potentially this exercise will be placing on the system.
Incorrect technique is another concern. Even slight errors in form can increase the risk of injury. Proper instruction and mindful execution are essential.
Strength Training: A Lifelong Pursuit
Our genetic makeup influences peak bone mass, but exercise plays a vital role in maximizing bone density. Bone mass typically begins to decline around age 40. Starting resistance training earlier helps achieve a higher peak, but benefits are realized at any age. According to the National Osteoporosis Foundation, approximately 54 million Americans have either osteoporosis or low bone density, highlighting the importance of preventative measures like strength training.

Beyond Weights: Resistance Training Options
Resistance training isn’t limited to traditional weights. Activities like yoga and Pilates utilize body weight for resistance, providing a great entry point. However, Way points out that bodyweight exercises may eventually reach a “ceiling effect,” requiring external weights—whether gym equipment or household items like canned goods—to continue challenging muscles.
The key, Way stresses, is simplicity. A routine of five to eight exercises targeting major muscle groups, performed in two to three sets of eight to 15 repetitions, can be highly effective. It actually can be pretty simple.
Ultimately, the most effective exercise is the one you enjoy. Resistance training offers a wealth of benefits, making it a worthwhile addition to any fitness regimen.
