Staying Focused During Exercise

Previously, when keeping track of the number of repetitions of a particular exercise, I've simply counted 1, 2, 3 onwards. Because counting like this is so automatic it's easy to count and let ones mind wander off. Lately, I've been counting not from 1 to 50 but from 2 to 229 using prime numbers. These fifty primes are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229

Counting this way requires concentration and thus the likelihood of losing focus is reduced. Combining this form of counting along with kinesthetic focus is ideal. The term "kinesthetic" means "relating to a person's awareness of the position and movement of the parts of the body by means of sensory organs (proprioceptors) in the muscles and joints". An alternative would be to count in a foreign language. I'm familiar with Indonesian so I could use that.

Mindfulness when exercising is simply mindfulness applied to exercise. See Figure 1. 

1. You take up a position rather than take a seat. 
   
   
2. You decide on the number of repetitions rather than setting a time limit.
    
3. You notice your body as you exercise (kinesthesia). 
   
   
4. You feel your breath which is very important and yet something I mostly neglect.
   
   
5. You notice when your mind has wandered (the special counting helps).
   
   
6. You are kind to your ageing body by not pushing it beyond its comfortable limits.
