And she explained that him coming prematurely meant she stayed pretty small throughout the entire pregnancy.
‘I didn’t get that last month of, like, you know, misery that some women go through,’ she explained.
The new mother said she ‘didn’t feel too much pressure’ to slim down following the birth, adding, ‘I gave myself so much grace.’
She revealed that she isn’t on a diet, but instead, she focuses on ‘eating as clean as she can.’
She also credits breastfeeding and pumping with helping her to ‘boost her metabolism’ and ‘burn calories.’
‘I have no idea when the photoshoot is so all I’m doing is just eating as clean as I can, but I’m still splurging,’ she dished.
‘Like, I had four dinner rolls last night at this charity event as well as my meal. I haven’t yet been on a diet since delivering.
‘I’ve been breastfeeding a ton – I’m pumping, nursing my child – and I think that has really burned a lot of calories and really boosted my metabolism. I kind of bounced back pretty quick if I’m honest.’

As for her workout routine, Jena revealed that she’s been training with New York City-based fitness coach Olivia Figueroa.
She said they do virtual sessions together, since she lives in Jupiter, Florida, with her husband and son, while Olivia is in Manhattan.
‘I literally set my phone on like a little tripod, and it’s almost like she’s there in the gym with me, telling me what to do,’ she explained.
‘I trained with her the year I got married, and I feel like I was in the best shape of my entire life. So I am working with her again.’
The SI Swimsuit Rookie said she loves to ‘mix it up,’ so she also takes various workout classes throughout the week – including Pure Barre.

‘I’m just trying to tone up as much as I can because I wanna feel like my best. My background is pageants and swimsuit modeling, so I feel like myself [when I look my best], she continued. ‘But I’m not putting any pressure on myself.’
Jena said her main focus recently has been weight training, which she got into after discovering a video on Instagram in which a woman claimed that lifting gave her a ‘big booty.’
‘Something about that video just stuck into my head, so I’ve been working on just upping my weights a little bit,’ she added.
‘I can get into this sweet spot and get kind of in a plateau of working out, so I upped my weights after seeing her video because I was so impressed by what she did with her fitness. I’m trying to lift heavier. Trying to build a booty.’
