If you are looking to build strength on the deadlift I recommend doing full dead stop reps as opposed to touch and go. For a lot of people the hardest portion of the deadlift is the initial pull off from the floor. By using touch and go reps you are taking this part out of the lift by using the stretch reflex of the muscles.
When is the best time to go to the gym? Is it better to go first thing in the morning? Do you burn more fat if you train in the morning? Does it even matter? Well let's put it into perspective.
I think a personal trainer is someone you go to because you want to get fit or you want to get into shape. They can assist you in your fitness journey. Their knowledge is good enough to help you but probably not enough to really take you from A to B. I think their knowledge is fairly limited which is more often than not due to lack of experience.
I’ve been powerlifting for just under a year now. I’ve got 2 competitions under my belt and I plan to do more in the future. Since starting I've had a few people say to me they would love to try it but they are not strong enough.
My advice to you is to sign up to a competition a few months away and start training for it. If you can get a coach, great, if not do some research and plan your own training cycle. There is no point waiting until you think you are strong enough because in my opinion you will never think you will be strong enough. Let me explain.
