HIIT cardio and weighted core in 40 minutes: two explosive circuits with low-impact options, then a dumbbell ab finisher.
Day 58 of HR12WEEK 5.0 opens with a warm-up and two HIIT circuits of 40 seconds on and 20 off, two straight sets of each exercise, built from powerful, explosive moves. A third circuit of weighted ab exercises, with a mat and a medium dumbbell, finishes the core. Low-impact modifications are offered throughout, and the video runs about 41 minutes.

Equipment setup
Who Is It For?
Active people with a mat and a medium dumbbell who want a sweaty HIIT session, with the option of low-impact versions.
Who Is It Not For?
Not ideal if you want something gentle or avoid planks and floor work: the core circuit is weighted and the HIIT rounds are intense.
Key Benefits
Builds power, endurance and core strength in one session, with low-impact options that stay just as effective.
Things to Keep in Mind
Take the low-impact versions whenever you need them, land softly on jumps and protect your lower back during weighted ab work and planks.
