We took inspiration from Craig Massey on this episode and dug a little deeper into finding that sweet spot of challenge which will make or break your fitness success. Too hard? You lose motivation, get injured, find yourself in pain, feel disheartened. Too easy? You're bored, uninspired, not progressing, stagnant. Sweet spot? You're progressing, challenged, motivated, making mistakes and learning – it's what we should all be hunting for!
