Most training injuries we see are not freak accidents. They are loading errors: too much, too soon, with too little recovery in between. The fix is unglamorous, and it comes from the World Health Organization (WHO) and the American College of Sports Medicine (ACSM): progress gradually, strength-train regularly, and let recovery do its half of the work. Here is how we explain it to our own patients.
The Short Version
- Increase cardio intensity by no more than 10% per week
- Aim for 2–3 strength training sessions weekly, targeting 8–12 reps
- Listen to your body: intensify when it's easy, rest when you're fatigued
- Use the "2 for 2 Rule" to know when to increase load
Cardio Progression: From Beginner to Advanced
The WHO's baseline for adults is 150 minutes of moderate-intensity cardio or 75 minutes of high-intensity cardio a week. Once that feels manageable, add no more than 10% a week. Running, cycling, swimming, dance: mixing modalities all counts, and variety keeps both the body and the motivation going.
Strength Training: The 8–12 Rep Range
ACSM guidelines suggest 2–3 strength sessions a week in the 8–12 rep range. That range builds both strength and muscular endurance: enough to force adaptation, manageable enough to recover from. Once 12 reps feel easy across two consecutive sessions, add resistance.
The "2 for 2 Rule"
The 2 for 2 rule is simple: if you can do two reps beyond your target on two consecutive workouts, increase the weight. It keeps progression continuous without the sudden jumps that cause overuse injuries.
Listening to Your Body: The Most Important Tool
No programme survives contact with the human body unchanged. If a session consistently feels too easy, that is your signal to progress. If you are carrying significant soreness, fatigue, or pain, rest. Rest days are not setbacks; they are when adaptation happens. Training is the trigger. Sleep and recovery are the response.
The Physio Perspective on Progression
Pain during training is not automatically a reason to stop, but it is always a reason to assess. A physiotherapist can distinguish between productive discomfort (normal muscle effort and fatigue) and tissue warning signals (joint pain, tendon pain, nerve symptoms) that require modification. Getting this distinction right is what protects your long-term training capacity.
"Progress, no matter how small, is still progress. Consistency beats intensity: every time."
