A professional boxer turned personal trainer has revealed how boxing is the key to honing the perfect summer body.
Glen Austin, from Sydney, said boxing is the best full-body workout for strengthening arms, legs and core, as well as improving balance and coordination.
Glen, who competed professionally in mixed martial arts and now acts as the Combat Sports Commissioner for Western Australia, also shared the exact exercises to tone your stomach and build glute muscles.

Glen also shared his best stomach toning and glute building exercises, including ab wheel roll outs and L-sit hanging raises
Glen recently teamed up with trainer Ben Mills to launch Shelter Boxing Academy, a boxing training camp at Shelter Gym, a ‘non-intimidating’ boutique space in Sydney’s Double Bay.
‘Boxing gives you the ability to ‘train like the pros, without the blows’,’ Glen told FEMAIL.
‘Through boxing, you develop speed and strength in your arms, legs and core. Your cardiovascular fitness and coordination are bi-products of the exercise.
‘When you’re in a boxing studio, you’re present and in the moment. It’s certainly something that serves as a form of escape from our busy lives.’

Asked the age old question about how to tone your stomach, Glen admitted the adage ‘abs are made in the kitchen’ is largely accurate.
‘This is best achieved in the kitchen! If we were to talk about toning stomachs in the gym, keep it simple,’ he said.
‘Ab wheel roll outs and L-sit hanging raises are best – it doesn’t have to be over complicated to be effective.’
To build a toned behind, Glen advised hitting the area directly with exercises that activate the gluteus muscles.
‘Progressively adding weights and reps is important to improve tone and growth over time,’ he said.
In terms of toning arms, Glen said it’s best to keep it old school with traditional bicep and tricep exercises.
His favourite full-body workout is spinning, which he tries to fit in three times a week.

Glen believes a mix of disciplines like spinning, boxing and Pilates is the key to maintaining a lean, toned physique
‘Three sessions a week is achievable for anyone who allocates time in their day to exercise, he said.
‘If I only trained three times a week, I would mix disciplines – for example, boxing, spinning and Pilates.’
Glen said rest and recovery is essential to sustaining an effective fitness routine.
‘It’s so important for avoiding injury and promoting growth,’ he said.
