Keep intensity high, volume low.
Give your body a reason to get stronger. This is done with high loads. Extra volume will add unnecessary fatigue and take away from the strength focus - which can sometimes be necessary depending where you are in your training
Separate your strength and endurance sessions ideally by 1 day or at LEAST 6hours.
Too close together and you will dilute the stimulus and send mixed signals to the body resulting in poor adaptations in both areas.
Train like an athlete, EAT like one too.
Fuel your body like the engine it is. This means plenty (and more) of nutritious food, a whole load of protein, and enough carbs to feed a family of 4.
Take your recovery seriously.
Stop neglecting the 22 hours a day outside of training, that’s where the magic happens. Sleep well, reduce external stressors where possible and learn to breathe properly.
Do these 4 things well and you’ll soon be making some rapid progress towards your hybrid goals.
