Think of it as the refreshed version of the insanely popularseven-minute workoutthat debuted in 2013.

Give the routine a tryit’s fast and doesn’t require anything other than a sturdy chair or bench.

(That’s only 14 or 21 minutes of work!)

Make It Easier:Keep your extended leg on the ground.

Make It Harder:Take five seconds to lower butt to chair.

Start standing with a slight bend in knees.

Push off left foot and jump to the right, landing on right foot.

As you land, watch that the right knee does not collapse inward.

Continue jumping side to side for 60 seconds.

Make It Easier:Step, rather than hop, side to side.

So it looks like: Jump-Jump-Stick-Jump-Jump-Stick.

Lie facedown with arms extended overhead with palms on floor.

(Your body will slide, not your hands.)

Now reset by releasing hands and extending arms overhead again.

Continue for 60 seconds.

Make It Easier:Tuck your toes and use your feet to help propel you forward.

Start in reverse table-top position with butt touching floor.

Keep shoulders rolled down and back.

Squeeze butt and lift hips into air, wrists should be under shoulders and ankles below knees.

Lift right arm and twist shoulders so that right arm crosses over torso reaching toward the opposite side.

Lower arm and tap butt on floor.

Repeat on opposite side and continue alternating for 60 seconds.

Make It Easier:Ditch the arm reach and focus on just the hip thrust.

Make It Harder:Lift your opposite foot off the floor as you raise your hips.

(So your right arm would reach while your left foot lifts.)
