When I first began working out with my trainer, she had me do 3 sets of tricep pushups against the wall, 15 repititions. No weights, just the wall, was the resistance. Easy you think? Well, for a lady that had very weak triceps and definitely a beginner…easy they were not. I could definitely feel the burn in the third set. We finished our workout and I was very tired. My arms felt like they were going to fall off.
The next day when I woke, my triceps were extremely sore. My trainer called to check on me. I told her about my tricep soreness. She explained that muscle soreness was a good thing. She explained that I needed to rest those muscles for at least 48 hours. She explained how the muscles had small tears and would grow back stronger. I had no clue, I believed her, and went about my day.
It is now 4 years later, I’m in school and know the scientific reason for muscle soreness. When you work your muscles at a high intensity (the definition is different for every person), you experience small microscopic tears in your muscle belly. These tears are sometimes referred to as “baby ankle sprains”. Why, baby ankle sprains? Well, like a sprained ankle which causes inflammation pockets, baby ankle sprains are on a more microscopic level located in the muscle belly and tendon of the muscle.
Usually the next day, you will experience soreness in these muscles known as delayed onset muscle soreness (DOMS). Why is this a good thing? Your body will build your muscle back even stronger than before and soon you will see adaptations. For instance, the exercise with the reps, weights, and sets become easier and soreness is no longer experienced. It is time to increase the intensity again. The one important rule you must follow however is sore muscles should be given at least 48 hours rest before working again. This allows ample time for repair and will avoid an injury.
I work out relatively high intensity, at least 5 times a week, and I still experience sore muscles. Do the same tricep pushups give me sore muscles?….well, no… I’m much stronger, I can do the pushups on the floor now and many many more. I now know that when my muscles are sore…. I worked them hard!… and that is a good thing!!! Adaptations are being made…I’m getting stronger.
So don’t be afraid…work those muscles!
