Painkillers are being used increasingly often in strength training and endurance sports such as cycling. Bodybuilders sometimes train with paracetamol and cyclists with tramadol.

There is also a natural way to enhance pain-relieving performance. This can be done with herbs and carries much less risk than the chemical method. Take a look at our, for example. herbal intra-workout drink.
