Kate Upton has been working hard on her body throughout her pregnancy.

The 26-year-old model is expecting her first child with her husband Justin Verlander and has been focusing on keeping her body in its best shape.

Her trainer Ben Bruno told E! News: ''A lot of the workouts Kate has been doing are based on the Strong4Me workouts. The main thing is that when you're pregnant, some days you have more energy than others and you just have to listen to your body. Kate is still exercising. It's a toned back version of what we were doing. I think when you're pregnant, it is not the time to try to set personal records in the gym so we dialled back. The main thing is you have to listen to your body so you know some days it's not in the cards to work out and that's okay.''

Meanwhile, the blonde beauty previously revealed her husband was more ''excited'' about her weird pregnancy cravings.

She said: ''Justin was the most excited about weird cravings. He kept being like, 'I can't wait for the pickle run in the middle of the night.' I'm like, 'Okay.' But I haven't had anything. I'm fine with all food ... I stopped working out for a month [because I] was so tired and there was so much travel. But I've been completely trying to stay healthy and work out through the pregnancy, and doing the best I can. It makes me feel better, honestly. What I'm working toward is different. Instead of working toward being super fit, I'm strengthening my pelvic [area] and doing a lot of hip thrusts, body-weight hip thrusts and lunges and squats to help with delivery and make it easier, hopefully. Fingers crossed.''
