Dina suggests avoiding weightlifting. "I don't lift weights," she told Runner's World. "There are lots of other ways to get power. It's not about how much weight you can throw around, but how well you use the power that you have." "Body-weight exercises offer many unique benefits for older adults. First of all, they are versatile: you can do them anywhere and don't need any equipment. Body-weight training is also ideal when returning after an injury or long layoff, when you need to build endurance and confidence," says Harvard Health.

Dina is a big fan of planking, an isometric core strength exercise that is great for the abs. She even has her own form of the exercise, revealing her trick to Runner's World. She starts in plank position, then, one arm at a time, moves into a press-up position. Then, she returns, one arm at a time, to the starting position. She tries to do five rotations in 60 seconds, keeping her hips level.

Because Dina is a sprinter, she spends a lot of her cardio time sprinting. She does three sets of 5x160m at race pace, with a 45 second break between reps. "When it feels OK rather than deadly, you know you're in good shape," she told Runner's World. 

Dina maintains a healthy diet fueled by protein. For breakfast she eats scrambled eggs with spinach and black coffee. "I need help in the morning," she told Runner's World. For lunch she eats salmon rice and vegetables. "I really love carrots and sweetcorn." Dinner consists of chicken, salad and rice. "It's fairly repetitive, which is hard for a foodie like me."

Cheat meals are "Definitely!" part of Dina's life, she dished to Cosmopolitan. "If I were constantly 'on' all the time I would eventually crash," she said. "I really like cupcakes, so once or twice a fortnight (sad how infrequent it is) I'll stop and get my favorite Cookies and Cream one from Lola's. They make me unbelievably happy." 

Dina allows herself to rest when she needs to destress. "As odd as it sounds I take a break – which might not seem productive with a deadline approaching. However, when I get stressed it feels like my brain shuts down and can't do anything efficiently, so I will listen to some music or make myself something to eat and then come back when I'm more relaxed," she told Cosmopolitan.
