@nkacyfitness: HIIT circuit 💦 If you’re bored doing cardio with machines, then try a HIIT circuit. I prefer it better over machine, you burn fat, challenge your heart rate, use your body weight and challenge yourself mentally. Workout: 3 rounds/ 40 sec on/ 20 off #fit #hiitworkout #hiit #workout #fitnessmotivation #Fitness #cardio
