"Efficient Bodyweight Workout for Busy Individuals: 3 Exercises to Stay Fit"

McMaster University exercise scientists have developed an 11-minute, low-impact workout that can be done during the busy holiday season. The routine consists of three exercises - squat thrusts, knee tucks, and mountain climbers - that engage muscles in both the upper and lower body without being too impactful on joints. The goal is to push yourself out of your comfort zone for 60 seconds during each exercise, reaching a 7 or 8 on a 10-point scale of effort. This workout can help maintain or improve fitness levels and is suitable for people of all ages and fitness levels.
