Kayla Itsines proudly embraces change. The SWEAT co-founder and trainer is always looking for ways to improve her world-famous workout platform, whether that means renaming her infamous "Bikini Body Guides" to be more body-positive or creating new inclusive programs that welcome people of all ages and fitness levels.
For her latest evolution, Itsines decided to upgrade her gym-based program, High-Intensity Strength with Kayla, to offer fans who might be heading back to the gym space post-COVID pandemic to really get back in action with a strategy in place.
Available exclusively on the SWEAT app beginning July 12, the program will offer 12 weeks of new programming designed to replace the current content on the app. The new High-Intensity Sweat with Kayla will feature a combination of high-intensity strength moves geared toward increasing fitness and building strength to further empower women to train in the gym with confidence.

Each of the weekly workouts takes roughly 30-45 minutes to complete. Three of them focus on either upper body, lower body, or full-body respectively, and there's an optional full-body cardio workout every week, as well. While this program is not best suited for beginners, Itsines does offer four optional beginner-friendly weeks for anyone looking to just get their feet wet.
Similar to the OG program, the revamped version will also rely on gym equipment, so this isn't the best program for you if you don't have a fully stocked home gym a la The Rock's Iron Paradise. That said, the program includes exercises that utilize larger gym equipment as well as smaller tools such as dumbbells, and some exercises require nothing at all.
High-Intensity Sweat with Kayla incorporates circuits with both supersets and trisets. The reps-based supersets challenge you by using progressive overload, which essentially means gradually increasing weight (or intensity or tempo) to build strength. The trisets are time-based, but also challenge you to steadily increase the workload via reps or weights. (Related: Does It Matter What Order You Perform Exercises In a Workout?)
Get a taste of Itsines' new High-Intensity Sweat with Kayla program with this exclusive 15-minute lower-body workout. This express session targets your quads, hamstrings, and glutes through a combination of compound strength movements and isolated endurance exercises.
Following the blueprint of her program, this workout is split into a superset and triset with the goal of improving both strength and stamina in these large, lower-body muscle groups. The best part? You don't need gym access for this workout. All you need is a kettlebell, a yoga mat, and some space to move around freely. No kettlebell? Just swap it out for one heavy dumbbell.

Keep in mind that the below routine doesn't include a specified warm-up or cool-down, but Istines recommends getting a few movements in ahead of the workout to increase your range of motion and reduce injury. For a warm-up, aim for three to five minutes of moderate-intensity cardio, such as jogging in place or jumping rope, to help rev up your heart rate and warm up your muscles. She also recommends doing some dynamic stretches — such as leg swings and torso twists.
Similarly, following your session, Itsines suggests doing a three to five-minute cool-down, which could include going for a short walk to slowly bring your heart rate back down to a resting state or practicing static stretching by holding a single position for at least 20 seconds. This will increase your flexibility and range of motion and also help protect you against cramping and lingering soreness.
