Leg day. Chest day. Back day. We’ve all seen it — the classic split routine where each gym session targets just one or two muscle groups. It looks disciplined, but here’s the catch: gym split routines come with built-in inefficiencies that cost you time and limit how your body really develops.

🏋️ The limits of gym split routines

Split routines are designed for hypertrophy — building bigger muscles — not so much for motor intelligence. That means your brain, breath, and body aren’t learning to move together. The main inefficiencies are clear:

• Inefficient time use: long rests and single-muscle focus drag sessions out while leaving large parts of the body untrained.
• Zero cross-body chain engagement: isolated sets don’t train systems to fire across left and right, upper and lower body.
• No fascia loading: fascia — the connective tissue web that stores elastic energy and supports resilience — gets very little work in isolation training.

⏱️ Full body workout vs split routine for time efficiency

Efficient full body workouts tackle strength, stamina, and coordination all at once. Instead of resting between isolated sets, you’re moving continuously — kettlebells, resistance bands, and bodyweight exercises flow into each other. This saves time, keeps your heart rate up, and develops whole-body strength in a single session.

For example, suitcase carries with kettlebells light up the cross-body chain, improve grip strength, and train breath control, all in one movement. Here’s a deeper dive: kettlebell rack and suitcase carries.

🔄 Are split routines better than full body workouts?

For bodybuilders chasing maximum muscle size, split routines still have a role. But for most people who want fitness, resilience, and time efficiency, full body training offers far more. You get coordination, stamina, and real-world strength in less time. It’s about training smarter, not just longer.

Full body sessions also lend themselves to community training. Outdoors, they feel more natural, energising, and social than being stuck scrolling between sets. In Southsea, Portsmouth, we run sessions by the ocean where kettlebells, active stretches, and bodyweight drills are woven together.
