Kettlebell complexes, where you perform multiple exercises back-to-back without setting the weight down, are among the most time-efficient training methods for simultaneous fat loss and muscle building.
This five-move complex chains together kettlebell swings, cleans, front squats, presses, and Turkish get-ups into one seamless flow. Perform five reps of each movement before switching sides for a total of 50 reps per round.
Start with a moderate kettlebell weight and aim for four to six rounds with 90 seconds of rest between rounds. The entire session takes about 25 minutes and can burn upwards of 400 calories while building functional total-body strength.
