hi don
your cardio vascular fitness is whats important for endurance. whether your a tiler, lawyer, brick layer or brain surgeon.
try and cut down on processed/bad carbohydrates..cakes, sweets, white bread, pastries. eat wholemeal sandwiches, more fruit and veg and lean protein and the big one is drink more water during the day, 2-3 litres. it will surpress your hunger, will neutralise your blood sugar levels, rehydrate your body and give your more energy. also the weight will come off!!!
do exercises that you enjoy, if you hate training then you wont stick at it. try anything.
i take my training and health really seriously but i enjoy it. being fit combats stress and reduces lots of illness, ie heart disease, strokes, cancer, depression the list is endless........dont let your weight get out of hand. your weight is similar to tiling, easy to put on but a b*****d to get off!!!!
