Jenelle Evans is in great shape and she's not afraid to show it.

In one of her latest Instagram photos, the Teen Mom 2 star shows off her weight loss and toned arms and reveals how she got fit.

"The Teen Mom 2 star is once again flaunting her impressive weight loss for her Instagram followers — and we don't think the 24-year-old has ever looked better," In Touch Weekly reported on Thursday.

"Drinking the @flattummytea detox before my morning workouts has been boosting my energy! I've been busy all day & not once have I felt groggy. This gives me the energy I NEED! My body is feeling & looking great, no more bloating," she wrote to fans with the photo below.

In other Jenelle Evans news, she and her boyfriend, David Eason, appear to be going strong several months into their relationship.

"He's a very hard worker, and I love that about him," Evans told PEOPLE Magazine in March. "He doesn't care about me making money, or how much I get, he still pays his own bills, and he still gives me money for rent and everything, which I've never had any boyfriend do!"

He's also great with Evans' kids, Jae, 6, and Kaiser, 1.

"Jace absolutely loves him, [he] always wants to be around him," Evans said. "And he has an 8-year-old daughter that comes and spends the weekends along with Jace, so they get along very well and everyone is just really happy."

"[I] can definitely see him as a great person [to have kids with]," Evans said, but for now, they are "taking things slow."

"We're not looking into marriage or kids or [anything] like that," she said. "I even said on camera, I said: 'I'll be miserable for the rest of my life as long as I have my family togethe.' But honestly, it's really about being happy, and if you're not happy, your kids aren't going to happy, and that's the most important thing."
