How do I do more lengths?!
I am working on increasing my laps. I use to be only able to do one lap before stopping (25m). Since then I have concentrated on my inhale and exhale technique, have tried relaxing my head and neck in the water, slowing down my strokes. I am now able to do two lengths, stop, 2 lengths, stop, etc.
I want to be able to push it further and do more laps without stopping but my heart rate gets so high I feel like I have to stop.
Is this normal? When will I be able to push through this "wall"? It is getting frustrating. Any suggestions?
