@frustratedhusband I wish there was a clear explanation for each injury I’ve had and a clear explanation for how to prevent injuries, but the human body and its response to stress in a dynamic environment is too complex for that.
The times it was clear, it came down to not a great balance between stress and recovery. For example, I tore my hamstring in 2009 on a set of sumo deadlifts. But I was doing 5 HIIT sessions a week including some on-ground sprinting while training legs, heavy, and near failure with moderate volume twice per week…oh and I was 4 months into contest prep. Finally, I had built up to this very high level of HIIT training quite quickly rather than gradually.
Don’t do that.
However, I mentioned in another question a neck injury I had that resulted in a slipped disc that I almost got surgery for. That occurred during a deload on a light set of OHP in the offseason
Broadly, my advice is to slowly acclimate to higher stresses. Want to increase volume? Ok, but don’t do so more than 20% and sit on that for a while. Want to train closer to failure? Ok, but don’t do so by more than 1 RIR, and not while also increasing volume. Don’t do either when sleep or nutrition isn’t in place to support the added demand. Use consistent form, implement autoregulation for load selection and deloads, and when using new exercises or higher volumes or intensity than you’re accustomed to, use intro weeks to bridge into it.
