I never liked relying too much on something. I have friends who couldn’t train without taking their “pre-workout” a certain number of minutes before the session. Training was like a space shuttle launch- the timing of their energy drink, the clothing, belt, knee sleeves, warm-ups- everything must be carefully orchestrated.
Now, I am a fan of having a routine. Don’t get me wrong. But life will throw curve balls at you, and it always feels good for me to be able to adapt to new situations when training isn’t optimal. I can squat without my lifting shoes. I don’t need to wear knee sleeves, and I don’t have to wear a belt. If I’m in a hotel I can create workouts using dumbbells or bodyweight exercises.
Be able to adapt to your surroundings. If you always train at the same gym, on the same rack, try using a new one. Take your squat shoes occasionally and use your sneakers. Do some push-ups when you’re stuck inside in the winter. It forces you mentally to get stronger, as you’re deliberately messing with your routine.
