Get Strong Fast: Chris Hemsworth's 20-Minute Dumbbell Workout
A high-intensity, full-body routine to build muscle and burn fat with just two adjustable weights.

Maximize Muscle Gains on a Tight Schedule
Feeling pressed for time during the holidays or as your schedule normalizes in the new year? Don't let a busy lifestyle derail your fitness goals. With a focused approach, you can still build muscle and stay in shape. Discover how a quick 20-minute dumbbell workout can make a significant difference, even when time is scarce.
Essential Equipment for Effective Home Workouts
All you need to get started is a set of adjustable dumbbells. These versatile weights are perfect for home workouts because they combine multiple weight levels into one compact set. Adjustable dumbbells save space and allow you to quickly change the load between exercises, making it easy to increase intensity as you grow stronger.
Kickstart Your Routine with Centr's 20-Minute Workout
Set aside a small space, roll out a yoga mat, and dive into a dynamic session from Centr, the workout app developed by Chris Hemsworth. Led by expert trainers Luke Zocchi and Maricris Lapaix, this routine is designed to target multiple muscle groups. Their guidance ensures each exercise is performed correctly, maximizing effectiveness and safety.
Embrace High-Intensity Resistance Training (HIRT)
HIRT combines strength-building exercises with heart-pumping intensity, making it an efficient way to work out. This method involves pushing your muscles hard for short bursts, taking brief rests, and moving swiftly to the next exercise. It's an ideal strategy for those looking to pack a powerful workout into a limited timeframe.
HIRT vs. HIIT: Boosting Your Metabolism and Strength
While similar to High-Intensity Interval Training (HIIT), HIRT focuses more on muscle growth rather than just cardio. Both increase your heart rate and burn more calories compared to steady-paced routines. Additionally, HIRT not only helps in fat loss but also enhances muscle strength, providing a dual benefit for overall fitness.
Centr’s Hybrid Strong Program: Your Path to Fitness
Launching on December 30, 2024, Centr's Hybrid Strong is a six-week program featuring three new HIRT workouts each week alongside dedicated cardio sessions. Whether you prefer treadmill workouts or equipment-free classes, this program adapts to your needs. It's a fantastic way to start the new year with a balanced focus on strength and cardiovascular health.
