A descending ladder of sit-ups and mountain climbers. Both moves challenge your abs in different ways: sit-ups in a time under tension manner, mountain climbers as dynamic ab work so again, a superset style ladder.
Get ready...this side of abs may start off mild but gets spicy real quick!
Get ready to light up your abs/core with this bodyweight only time under tension sizzler!
I like to call this circuit the “OG of time under tension oblique work” (with a dash of Stoked Spice of course). Drop down and GO!
