In this YouTube video, we have another dumbbell workout by Funk Roberts. This one is 25 minutes long and utilizes metabolic conditioning and high intensity interval training (HIIT.)

There are 8 exercises, several of which are combinations. That way, you can work multiple muscle groups in less time. You perform as many reps of each exercise as possible in 40 seconds, rest 20 seconds, and perform the next exercise in the sequence. The 8 exercises will be done for 3 rounds.

How much weight you use is your choice, but it’s good to have dumbbells ranging from 15 lbs to 30 lbs. If you use a lighter weight, you can perform more reps and build muscle. If you use heavy weights, you’ll perform fewer reps and build strength. By using HIIT principles, your body will burn fat for days after doing the workout.
