The 30 year old emphasises the importance of cultivating a positive and supportive environment to train in. "I've grown up playing rugby, and sport is all about lifting each other to be the best you can be. I bring that to the gym, so everyone feels supported. We have fun and train hard."
Jazza takes a smorgasbord approach to training. Think: mash-ups of CrossFit-inspired moves and functional heavy lifting. Boom! His fave workouts for torching fat? HIIT with added weight training. And don't forget nutrition- "Nourish- don't punish- yourself," says the dad of one, who's also a Body Science ambassador.
"Body love is important not only for your physical health but your mental healthy, too."
Train like Jazza
"Women come to me with lower-back problems, so I'd say work on your core." His fave move? The plank.
"Find an active community of people, so you can motivate, help and train with each other."
This guy can carry a tune- he once sang back-up for Joel Madden on The Voice.
