Sodium plays an important role in the regulation of bodily fluids. It transports potassium to muscle cells which helps contribute to a much fuller appearance if lifting weights and strength training.
In moderate amounts, it can actually really help with your training. It helps you to train harder, improve muscle development and it gives your body that lean look.
Spikes in sodium may contribute to short-term water retention and high blood pressure, so do your best to keep things consistent. When you consume a consistent amount, your body will become accustomed to it over time. (No belly bloat).
Keep sodium (and water) intake consistent and don’t feel the need to restrict if you want to look your best.
