Exercise Demonstrations

Take a quick look at the moves in the demo videos below, then follow the complete workout guide.

1. Dumbbell Suitcase Deadlift

Inspired by old-fashioned suitcases, this move targets your core, grip, and legs. Perform it quickly but maintain proper form. Tap the dumbbells to the floor with each rep, then stand up with force. Keep your chest elevated, back straight, and focus on the hip hinge. Engaging your glutes helps protect your lower back.

2. Dumbbell Devil Press

This challenging exercise combines a burpee, a slight swing, and a snatch, enhancing full-body strength and endurance. Choosing the right dumbbell weight helps you maintain a smooth rhythm, with minimal pauses between reps. For example, divide 20 reps into two sets of 10 to keep the pace manageable.

3. Dumbbell Squat Clean

Squat cleans build leg and core power while training you to lift weights from the floor to your shoulders. This exercise demands stability and coordination between both sides of the body. Focus on a strong lift, shelf the weights at your shoulders, then descend fully into a squat. Execute each rep cleanly, ensuring depth in your squat before driving back up.

Workout Structure

Begin with 20 reps per exercise, resting minimally between moves. You can alternate arms using one dumbbell or extend the time cap for extra flexibility. Reduce the reps by two each round and continue until reaching the 15-minute limit. Adjust starting reps or duration as needed. Choose a weight that allows you to complete reps efficiently, resting only briefly if necessary. Aim to perform 10-12 reps per move without pausing.

Stay consistent, progress gradually, and embrace the challenge of the devil press!
