I seem to have a problem currently with my weight sessions .

One day I will be doing my work out just fine, lifting the same weights as I always do with no problems at all. The next session I might not be able to lift fuck all.

I thought it may be something to do with energy levels so had a banana and a choccy bar before I went for a session the other day (To give me both slow and fast release energy) and that didnt seem to solve it, and nor did giving myself more rest between sessions.

Anyone have any ideas?? It is really starting to wind me up....
