The high-intensity interval training wave is still cresting, thanks to its positive metabolic effects and its ability to elicit results. HIIT raises the anaerobic threshold and creates excess postexercise oxygen consumption (EPOC), or oxygen debt. Simply put, metabolism stays elevated for longer after an intense workout than it does after low-intensity exercise.
Tabata™—one of many HIIT protocols—alternates 20 seconds of very hard work with 10 seconds of all-out rest, repeated eight times for a 4-minute set. The metabolic workout presented here is inspired by the original concept, created by Izumi Tabata, and combines intense cardio with strength supersets, which serve as active rest.
Tabata-Inspired Blast Details
Total time: 50 minutes
Equipment needed: a step, dumbbells and resistance tubing
Music: Create a playlist that generally reflects your audience, if you know what demographic to expect. Music should be upbeat and energetic; 130–135 beats per minute.
- Alternate between HIIT intervals and strength supersets (active recovery). Each 8-minute block includes a 4-minute Tabata-inspired cardio set, a 3-minute superset (includes transition time) and a 1-minute recovery. The recovery allows you to start coaching the next set.
- Vary the tempo for strength exercises so you challenge the body in different ways.
- Make it clear upfront (perhaps on the schedule) that HIIT workouts are not recommended for people brand-new to exercise.
- Offer regressions and progressions for each move, since you’ll likely have participants of all abilities in your classes.
- Be a coach! Correct technique and encourage people to progress at their own pace. Remind them to find the option that works for them. An option is only a good choice if they can execute it correctly.
- Educate class members about the harmful effects of overtraining. The harder the effort, the shorter the duration should be, to reduce the risk of overuse injuries. Participants should engage in HIIT no more than three times per week.
- Clearly communicate intensity during the HIIT sets, which are designed to reach maximum intensity. To keep this level of effort for 8 sets in a row with perfect technique is difficult for even the most elite athlete. Encourage people and let them know that completing all 8 sets may not be realistic. It’s okay to take breaks, skip a set (or two) and come back stronger for the next one.
- Encourage participants to use a heavy weight for the supersets and to go to fatigue if they want to see results.
- Coach participants on how to protect their joints by “absorbing” the landing, since many of these moves are power-based.
Warmup (5 minutes)
Prepare participants for the workout by leading them through a thorough, total-body warmup. Good options to include:
- basic squat with lifted heels (reach arms up)
- yoga flow: upward-facing dog alternating with downward-facing dog, 4x
- walk-out planks
- slow mountain climbers
- reverse lunges
Work Phase (40 minutes)
- Stand at step end (with bench horizontal), one foot on step, other foot on floor.
- Cross outside leg in front to touch step with toes.
- Jump to wide position—one foot on bench and one foot off—into squat. Absorb landing.
- Perform 4x each side.
- Do prone fly, with rib cage on step and head/chest off.
- Do incline pushup on step.
- Perform 15 reps each, 2x.
HIIT: Shuffle Straddle and Step-Tap
For sets 1, 3, 5 and 7:
- Do straddle-step, shuffling forward to end (feet are on floor).
- Squat-jump, touching floor at end of step.
- Repeat, moving backward to other end of step.
For sets 2, 4, 6 and 8:
- Do alternating floor taps from top of step.
- Add power jump to switch legs.
- Get low to touch step with opposite hand as toe touches floor.
- From plank position, hands on step, rotate feet and torso as you drop one hip closer to floor; alternate.
- Lie supine on step and touch ankle as you do a crunch.
- Do 1 minute of each move.
HIIT: Speed Straddle and Skaters
For sets 1, 3, 5 and 7:
- Do speed straddle (up, up, down, down) on step as fast as you can.
For sets 2, 4, 6 and 7:
- Jump side to side, doing skaters on floor. Touch step at ends.
- Do band walk for 1 minute. Step on center of band while holding handles. Take two steps right and then two steps left.
- Do biceps curl, varying tempo, 15 reps.
