Low-Impact HIIT Cardio and Core Circuits
17/1711 – Low-Impact HIIT Cardio and Core Circuits
This workout serves as Day 7 of our 10-day Challenge, Functionally Fit with Nicole, but can also serve as a standalone workout.
Focus & Benefits: Get ready to dive into some HIIT cardio and core intervals, no jumping needed! While this workout can be completed bodyweight only, I’ll be using light weights for many of the exercises. In each 3‑exercise circuit you’ll complete cardio exercises, each with an emphasis on core! To wrap things up, we’ll tackle a 4‑minute abs finisher. Grab some light dumbbells and let’s get our sweat on.
Equipment: Light dumbbells (I use 3 and 5 lb) and an optional mat.
Tips & Helpful Information: We’re taking on this workout tabata-style! This means short bursts of activity, paired with shorter periods of rest. Each of our four circuits has 3 exercises, which we’ll complete for 2 rounds, 20 seconds on / 10 seconds off. Press pause anytime you need more rest!
There’s no doubt, tabata-style workouts can be tough because they challenge your anaerobic system, followed by little rest. But, the good news today is that our movements are all low-impact with the ability to be modified and move at your speed. So, feel free to make it a burner OR more of a moderate routine. Either way, it will be effective!
While our main circuits have a fair amount of abdominal and core stability work mixed into the cardio, I’ve added a short, 4‑minute core finisher onto the end to fill in any gaps.
To make this more wrist-friendly, you may choose to opt out of the spider plank, inchworms, and bear hover. Feel free to swap another exercise from this workout or choose something completely different that feels good. You’ll see me make fists from time to time in plank-type exercises to help neutralize the wrist joint and relieve pressure.
Difficulty & Modifications Explained: This is rated a 3 out of 5 due to the low-impact nature and scalability of the exercises. Your perceived exertion level could be great or less, depending on weights used, modifications taken, and/or speed at which you move.
Closing Note: Remember, whenever you come to a workout you’re choosing to show up for yourself. No one else. Give yourself what you need today whether that’s an intense sweat-sesh, low key movement, or anything in between. High five!
