It might seem counterintuitive to work out if you’re tired and groggy in the a.m., but research shows moving your body is linked to better focus and energy. Specifically, science suggests doing high-intensity interval training, or HIIT.

In a February 2020 study published in the journal Brain Sciences, researchers assigned participants into two groups: One who did HIIT and another who did moderate-intensity continuous exercise for six weeks.

People in the HIIT group performed 15-second intervals of work at 100 percent effort with 15 seconds of recovery in between. For two weeks, they did intervals of two sets for 20 minutes each (40 minutes total), and then the total time was increased to 45 minutes for the remaining four weeks.

Meanwhile, the moderate-intensity continuous exercise group cycled at 60 percent effort for 34 minutes and then increased to 39 minutes for the remaining four weeks.

At the end of the experiment, the researchers ran cognitive tests and found that the HIIT group showed a significant increase in attention and focus, decision making, working memory, and executive function compared to the moderate-intensity exercise group.

But you don’t have to hop on a bike to get the benefits. Any HIIT workout will do the trick, so long as you’re pushing yourself to the max and taking short rest breaks.

We spoke to Miriam Shestack, CPT, a HIIT group fitness instructor at Equinox and personal run coach in NYC, for a quick 10-minute HIIT morning workout you can try instead of hitting snooze.

A 10-minute morning HIIT workout to start your day

You’ll do three sets of a HIIT sequence. Each set has two moves, and you’ll repeat each set for three rounds for a total of 10 minutes.

You’ll need one pair of dumbbells to perform some of these moves, so pick a set that feels comfortable to do both upper- and lower-body exercises. Shestack recommends choosing 10- to 15-pound weights.

Here’s the lowdown:

Set 1

• 20 seconds of squat jumps
• 10 seconds rest
• 20 seconds of reverse lunge with biceps curl, alternating legs
• 10 seconds rest

Set 2

• 20 seconds of push presses
• 10 seconds rest
• 20 seconds of bent-over rows
• 10 seconds rest

Set 3

• 20 seconds of lateral lunges, alternating sides
• 10 seconds rest
• 20 seconds of plank jacks
• 10 seconds rest

7. Repeat for 20 seconds.

3. Push press
