The gym is not always the problem. The problem is getting there. Packing a bag, driving, finding a parking space, waiting for a machine. On a dark November evening, that is often enough to make you stay home.
So bring the gym home instead. A single kettlebell takes up less space than a pair of shoes, and together with your own body weight it trains every big muscle group: legs, hips, back, chest, shoulders and core. If you read Strength Training for Beginners, this is the natural next step.
Why a kettlebell?
A kettlebell is a ball of iron with a handle. Because the weight sits below the handle and not in your hand, the body has to work harder to control it. That makes even simple exercises train grip, balance and the deep muscles around the trunk.
- Strength and fitness at the same time. Swings and fast circuits raise the pulse like interval training, while the muscles get real resistance.
- A stronger back. In a Danish study from 2011 (Jay et al.), office workers who trained with kettlebells for 8 weeks had less pain in the lower back, neck and shoulders, and a stronger back.
- More power. A study in the Journal of Strength and Conditioning Research (Lake and Lauder, 2012) found that 6 weeks of kettlebell swings improved both maximum strength and jumping power.
- No excuses. The kettlebell is in the corner. You can train while the coffee brews.
Choose the right weight
The most common mistake is buying one that is too light. The leg and hip exercises need more weight than you think. A common starting point:
- Women: 8 to 12 kg. If you have trained before, 12 kg.
- Men: 12 to 16 kg. If you have trained before, 16 kg.
- Over 65, or new to training: start at the lower end and add a second, heavier one later.
If you can afford two, buy one light for the arms and one heavier for the legs and the swing. Choose one in cast iron or steel with a smooth handle that is wide enough for both hands.
Six exercises to start with
- Goblet squat. Hold the kettlebell by the horns in front of your chest. Sit down between your heels, chest up, and stand up with power. Trains legs and buttocks.
- Kettlebell deadlift. The kettlebell on the floor between your feet. Push your hips back, keep your back straight, grab the handle and stand up by pushing your hips forward. The most important exercise to learn, because it teaches the hip hinge.
- One-arm row. One hand on a chair or a bench, the kettlebell in the other. Pull it up towards your hip and lower it slowly. Trains the back.
- Push-ups. No kettlebell needed. Against the kitchen counter, on your knees or on your toes, whatever lets you do 8 to 12 good repetitions.
- Overhead press. The kettlebell resting at your shoulder, the handle in your hand. Press it straight up and lower it with control. One arm at a time. Trains shoulders and arms.
- Suitcase carry. Carry the kettlebell in one hand and walk slowly across the room, standing straight without leaning. Switch hands. Trains grip and core, and it is surprisingly hard.
The swing, once the deadlift is right
The kettlebell swing is the classic exercise, and for good reason. It trains the whole back of the body and raises your pulse fast. But it is a hip exercise, not an arm exercise or a squat.
- Stand with your feet a little wider than your hips, the kettlebell a step in front of you.
- Hike it back between your legs like a football snap, with your hips pushed back.
- Snap your hips forward hard. The kettlebell floats up to chest height by itself. The arms only guide it.
- Let it fall back, follow it with your hips, and repeat.
Start with sets of 10 and stop as soon as your back starts doing the work. Make sure you have free space in front of and behind you, and nothing breakable nearby.
Workout A: full body, 30 minutes
Two or three times a week, with at least one rest day in between. Warm up for five minutes first, for example with marching on the spot, arm circles and a few light squats.
- Goblet squat: 3 × 10
- One-arm row: 3 × 10 per arm
- Kettlebell deadlift: 3 × 10
- Push-ups: 3 × 8 to 12
- Overhead press: 2 × 8 per arm
- Suitcase carry: 2 × 30 seconds per hand
Rest one to two minutes between sets. Pick a weight where the last two or three repetitions feel hard but the form is still good.
Workout B: 20 minutes for busy days
Set a timer to go off at the start of every minute (an "EMOM", every minute on the minute). Do the exercise, rest for the rest of the minute, and repeat the round five times:
- Minute 1: 10 swings (or deadlifts if you are still learning)
- Minute 2: 8 goblet squats
- Minute 3: 6 rows per arm
- Minute 4: 8 push-ups
Five rounds of four minutes: 20 minutes, and every big muscle group has worked. The more fit you get, the less rest you will have.
Progress without buying more weights
- More repetitions. From 10 to 12, then to 15.
- Slower. Three seconds down in the squat and the row makes a light kettlebell feel heavy.
- One side at a time. A one-arm swing or a split squat with the kettlebell doubles the load on each side.
- Less rest. Cut the rest from 90 to 60 seconds.
- Write it down. When you can do 3 × 15 with good form, it is time for the next weight.
Safety, especially after 50
- Learn the deadlift before the swing. A video of yourself on your phone shows a lot. One session with a trainer is even better.
- Train barefoot or in flat shoes on a floor that does not slip.
- Keep your back neutral, never rounded, when you lift the kettlebell from the floor.
- Stop if it hurts in a joint. Muscle fatigue is fine, sharp pain is not.
- Talk to your doctor first if you have heart problems, high blood pressure that is not under control, or back or joint problems.
Between the sessions, a short walk or a few exercise snacks keep the body moving. Eat enough protein, sleep well (Recovery and Sleep) and finish the week with some mobility. Then that iron ball in the corner will give you more than many gym cards ever do.
