A budget-friendly kettlebell workout can torch 800 calories an hour, build strength, and boost heart health
At a time when gym memberships and fitness gear are soaring in cost, a humble £10 kettlebell may be your best secret weapon for weight loss and full-body conditioning. According to fitness coach Annie Murray, swinging one of these cannonball-shaped weights for just 15 to 20 minutes can burn up to 800 calories per hour, engage multiple muscle groups, and supercharge your metabolism.
Kettlebells aren’t new — but their resurgence is being fuelled by their unbeatable versatility, efficiency, and results. “A single kettlebell is all you need to strengthen your core, glutes, and upper body, and improve grip strength,” says Murray, founder of Annie’s Fitness and a specialist in strength training.
Compared to the hefty price tag of standard gym memberships, kettlebells offer a low-cost, high-reward alternative. A full-body workout requires just one piece of equipment and can be completed in under half an hour — no treadmill or weights rack required.
The Five Moves to Melt Fat
Murray recommends a circuit of five foundational kettlebell exercises. Beginners should perform each for 30 seconds with 30-second rests, completing three rounds. More advanced users can go for 40 seconds on, and 20 seconds off, over four rounds. The exercises include:
- Staggered Leg Deadlift & Row
Engages hamstrings, glutes, and upper back with controlled, single-sided movement. - Sumo Squat With Isometric Hold
Targets inner thighs, glutes, and core. Lift kettlebell to the chest while holding a deep squat. - Reverse Lunge
Performed bottom-up style to boost stability, grip strength, and balance. - Bicep Curl, Press & Tricep Extension
Three-in-one upper-body burner that builds arm strength and stability. - High Plank Pull-Through
Works core, shoulders, and stability — all while fighting rotation in a controlled plank.
Each movement is designed to engage multiple muscles, making every second count.

Beyond calorie-burning, kettlebells offer a host of other health perks. Research from the University of Wisconsin-La Crosse found that after just two months of twice-weekly training, participants improved their core strength by 70%. “Most kettlebell movements activate the core naturally,” says Murray, helping reduce back pain and improve everyday movement.
Older adults, in particular, stand to benefit. A 2024 study presented at the Integrative Physiology of Exercise conference found that seniors aged 60–80 who trained with kettlebells twice a week for six months significantly improved their grip strength, a key marker of longevity. Poor grip strength has been linked to an increased risk of heart disease and premature death.
Kettlebell routines also promote better posture, balance, and dynamic stability — which are crucial in preventing falls. “They strengthen stabilising muscles and train the body to move efficiently,” says Murray.
Perhaps most impressive is their cardiovascular boost. The high-intensity nature of kettlebell workouts elevates heart rate and improves metabolic health, contributing to lower “bad” cholesterol and better heart function over time.
FAQs With Fitness Expert Annie Murray
How often should you use kettlebells?
“Two to three sessions a week is ideal,” says Murray. That frequency builds strength and endurance without overtaxing the body.
Can kettlebell swings help reduce belly fat?
Absolutely. “They hit multiple muscle groups while keeping the heart rate high. Swings are one of the best exercises to boost metabolism and target fat.”
Which weight should you start with?
“Begin with a weight that allows for full control. Once you’ve nailed your form, you can gradually go heavier. You should feel challenged by the final reps — but never compromised on technique.”
Final Word
With just one kettlebell, you can dramatically improve strength, mobility, balance, and fat loss — all from your living room. Whether you’re short on time or skipping the gym to save money, this deceptively simple tool offers one of the best bang-for-your-buck fitness solutions out there.
