A woman in England lost over 100 pounds by rocking out to an online dance class during quarantine.

At her heaviest, Su Morgan weighed 259 pounds. She drank two liters of Dr. Pepper every day. A single mother of four, Morgan relied on takeout and quick snacks to fuel her busy days.

Morgan pursued a gastric bypass surgery when she reached almost 260 pounds. But doctors needed her to lose some weight naturally before they could do the operation.

So Morgan fixed her diet and fell in love with a virtual fitness class called “Rock Fit,” an online aerobics program set to heavy metal rock music.

In March 2020, Morgan started taking the class at least five days a week. Over the course of a year, she lost 118 pounds.

“I found the rock aerobics class during lockdown and I fell in love,” the 40-year-old said. “It’s the most fun I’ve ever had exercising and I would be dripping in sweat afterward. I do a lot for other people and I thought it was finally time I did something for myself.”

“I would pick easy dinners like pizza, chips and my portion sizes were always huge,” Morgan said. “I could easily drink two liters of Dr. Pepper a day, followed by a sharing bag of crisps as a snack.”

Mom to four daughters Aylssa, 14, Phoebe, 11, Taylor, 9, and Sophie, 3, Morgan said the secret to her success was finding an exercise program that she was passionate about.

“I love rock music and attending Download Festival,” she said. “The [Rock Fit] class is not available in my city so I was really lucky it was streamed online.”

“I was still eating the things I loved, just small portions,” Morgan said. “I can’t believe I did it all on my own and the weight was dropping away.”

Down to 141 pounds, Morgan is no longer pursuing gastric bypass surgery. But she hopes to have a tummy tuck to remove the excess skin on her belly after her major weight loss.

“I love and hate my body now,” she said. “I hate looking at my saggy tummy so much but I know it’s because I’ve worked really hard.”

“I’m really proud of myself and hopefully I can inspire others to do the same,” she added.
