Strength classes are designed to flow without waiting for equipment, mirrors, or devices, led by qualified personal trainers who provide guidance and encourage progression, making them suitable for beginners through to advanced lifters. Cardio classes run on Tuesdays, Thursdays, and Saturdays, covering styles like HIIT, Cardio Endurance, Tabata, and Hyrox, designed to complement the strength programme. All classes run for 45 minutes.
Blitz is owned by Gary Hancock, a former Canterbury police officer and experienced personal trainer with a background in rugby and competitive cycling, alongside manager and head strength coach Sam.

Blitz Fitness is a locally owned and operated gym in Halswell, Christchurch, built around a class-based training model that does things a little differently. Rather than a standard gym floor, Blitz runs strength classes three days a week and cardio classes on the other days, with every member given a progressive strength training program regardless of experience level.\n\n## What They're Known For\n\nBlitz's strength classes are designed to flow so there's no waiting for equipment, no mirrors, and no one on devices — making sessions time-efficient, specific, and interactive. Every strength class is run by qualified personal trainers who provide guidance, keep members safe, and encourage progression, making the format suitable for complete beginners through to advanced lifters.\n\nCardio classes at Blitz run on Tuesdays, Thursdays, and Saturdays, covering a variety of styles including HIIT, Cardio Endurance, Tabata, Hyrox, and more. These are designed to burn fat, build cardio performance, and complement the strength programme, with workouts built to challenge members \"at their level.\" All classes at Blitz run for 45 minutes.\n\nBeyond group classes, Blitz offers 1:1 Personal Training, which can include injury rehab, intensive strength or conditioning work, sports-specific training, or simply an option for anyone not yet comfortable in a group setting.\n\n## The People Behind Blitz\n\nBlitz is owned by Gary Hancock, who is deeply embedded in the Halswell community — he literally lives over the back fence from the gym. Gary is a father of two and spent time as a caretaker and School Board of Trustees member at Halswell Primary School. Before Blitz, he served in the Police in Canterbury for 18 years. Gary has been involved in sport throughout his life, playing several seasons of Division One rugby in Christchurch before moving into cycling, both on the road and track, representing at a national level. He is a qualified and experienced personal trainer who has coached a variety of teams and individuals.\n\nSam is the manager of Blitz and has been with the gym since it opened two years ago. As head strength coach, Sam writes all the strength programmes taught in studio and has become an experienced trainer working with athletes and everyday people alike, helping members work around personal challenges with safe and effective alternatives.\n\n## The Experience\n\nBlitz's philosophy centres on providing a fun, friendly, communal group fitness environment — a non-judgmental, supportive space for members to work toward their goals, whether that's feeling fitter, healthier, or happier. There's no joining fee and no fixed-term contracts, making it easy to get started, and free parking is available on site. Every class has trained staff, and the gym describes its community of members as an awesome, local one.\n\nAs the gym puts it: \"The only difference between ordinary and extraordinary is that little bit extra.\"\n\n## Visiting Blitz Fitness\n\nBlitz Fitness is located at 345 Halswell Road, Halswell, Christchurch, New Zealand.
