In-between sets trying to find that hero inside myself to dig in a bit harder, which often takes a lot of digging..
The power of the mind when training is absolutely key 
If you struggle with motivation then try a few of the following to help you during your workout!
1, Leave your phone in the locker – having access to emails and messages is a recipe for disaster when you’re trying to get a workout in!
2, Listen to motivational/empowering music – music can always change your mood and provoke an emotion ( Anything Linkin Park, The Prodigy, Jay Z, 50 Cent or any old school rap is always a winner)
3, Time your rest period in between each set this will allow you to keep your intensity up!
