Lowering Cortisol

[chunkymunkey]

I've been lifting to failure with my trainer and have just read an article that states, "[...] one study found that exclusively using the technique drastically increased resting levels of the stress hormone cortisol". I do two sessions a week, one set per exercise to failure (usually between 20-30 slow and controlled reps). They're full body sessions, and we usually target the big muscles from different angles.

Are there any particular products/ingredients that you guys think can help counteract this?

Do you think it's necessary to worry about it?

Cheers
