Cross-training
Cross-training means practising a different sport or type of exercise to support your main activity.
Definition
Cross-training is the practice of mixing in a second activity alongside your main one — for example, a runner adding some swimming or cycling, or a footballer using gym work. The added activity is chosen to complement the main sport rather than to replace it.
People cross-train to add variety to their routine, to keep training when their usual activity is not possible, and to build fitness in a slightly different way. It is a common idea across endurance sports and general fitness, and multi-sport athletes such as triathletes work across several disciplines by design.

Strategies
- Tapering and PeakingTapering and peaking is the strategy of easing training load before a key event so fitness stays high while fatigue clears, timing peak form for the day itself.
- Specialisation vs VersatilitySpecialisation versus versatility is the team-building and development trade-off between narrow role experts and adaptable all-rounders who cover several jobs.
Training methods
- Steady-State CardioSteady-state cardio means holding one comfortable, continuous pace for the whole session, building an aerobic base without the peaks of interval work.
- Circuit TrainingCircuit training moves you through a series of stations back to back with little rest, blending strength and cardio into one time-efficient session.
- Strength TrainingStrength training uses resistance — bodyweight, bands or weights — to challenge your muscles so they gradually adapt and get stronger over time.
- Mobility TrainingMobility training works on moving your joints actively through their full range, combining control and flexibility so movement feels free and easy.
- Flexibility TrainingFlexibility training uses stretching to gradually improve how far your muscles and joints can comfortably lengthen and move.
Recovery
- Rest daysRest days are planned days off from training that give the body and mind time to recover between harder sessions.
- Active recoveryActive recovery means very easy, gentle movement on lighter days to keep the body moving without adding hard training stress.
- WalkingWalking is simple, low-intensity movement that supports everyday activity and gentle recovery for almost anyone.
- Easy daysEasy days are deliberately gentle training days that keep the effort low so harder sessions can stay hard.
- Listening to your bodyListening to your body means paying attention to everyday signs like energy, sleep and soreness to guide how much you do.
