This is why you need to start varying your training intensity
You’ve heard it before from a PT - '“every session, I expect 100%” or “my goal is to kill you by the end of the session” or doesn’t actually say anything but every session you have with them is enough to make you feel absolutely wrecked after.
This may sound harsh, but your trainer probably lacks the skills to actually coach.
Your workouts across the week should vary in intensity. Yes, you will have some really hard sessions where 100% is what it requires. However, on other days/weeks, what is required is 70% - so you give exactly that.
Why does this matter?
To avoid burnout, promote adaptations and optimise recovery.
Reaching for 100% all the time has an upper limit and it is not sustainable. Hence why you may feel like you have the movement piece of your program on lock but you feel constantly stressed and fatigued. Training in itself is a ‘positive stress’, but if you are not recovering and going straight into another 100% session the next day, and then another one after that, you will eventually cause havoc on your hormones. Namely cortisol, which affects many different bodily functions.
The hard truth is, you don’t make your stress response better by just training more. This is not physiologically how it works. What you can do though is work from the ground up:
Are you getting quality sleep?
How is your nervous system day to day?
Do you go into every session with DOMs from the day before?
What is your fuelling like?
Do you have a tailored program that suits your goals?
You will be surprised how much proper recovery will elevate your training and take it to the next level!
