When it comes to training and body composition, the saying “ you get out what you put in” couldn’t be further from the truth. If you aren’t prepared to put the hard hours in at the gym even on the days you don’t fancy it then you can’t expect to see the changes in your physique and/or strength that you are looking for. The same goes for your diet.
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.
