Body & welness The #TBT workout. And, calm down.

The hottest fitness trend? Throwing it back to playground days.

sometimes being an adult is hard. So fitness instructors are taking workouts back to a simpler time: primary school.

These routines, which incorporate moves we learnt in PE class, are blowing up for a reason: they’re fun, says Nedra Lopez, trainer and founder of a fitness club. She developed this workout which you can do on a playground.

Grab a towel and do the circuit three times, resting 30 seconds between each. Do three sessions a week to feel stronger in a month. Remember to ask for your turn on the swing! (We only got the side-eye from a kid once.)

Bench dips

Where Park bench. Works Triceps, shoulders and back. Sit with your hands on the edge of the bench, fingers facing forward. Scoot your butt off and lower body by bending elbows 90 degrees (be sure movement comes from arms, not hips). Push back to start. Do 12.

Swing hamstring curls

Where Swing set. Works Glutes, hamstrings, abs and core. Lie on a towel on your back with heels planted on swing, legs bent. Squeeze your butt and lift hips, then extend your legs straight, pushing the swing away. Bend your knees and drag swing back to start. Do 15.

Tire elevated lunge

Where Tire swing. Works Hamstrings, quads and calves. Stand with your back to the swing, left foot behind you resting on tire. Bend your knee 90 degrees, lower into lunge. Push through your right heel to return to start. Do 15 per side.

Swinging abs

Where Swing set. Works Abs and shoulders. Start in the plank position with your forearms on the swing seat and your feet on the ground. Squeeze glutes and push swing away. Return to the starting position. Do 10 for a full set.
