Niche gym equipment like kettlebells and TRX suspension trainers are soaring in popularity. Kettlebells enhance full-body strength, while TRX systems use body weight for flexible workouts. Maintenance is key: Kettlebells should be stored in dry areas to avoid corrosion. TRX straps need periodic checks for fraying. Vintage kettlebell collections, dating back to the 1900s, highlight their enduring appeal. Fitness experts recommend combining regular cleaning with professional inspections to keep these versatile tools in top shape.
