Currently I've been working out about 4-5 days a week trying to get in about 6-7 different lifts in per day. Focusing on a major muscle group each day for example Legs day 1, Arms day 2, chest day 3 etc. Recently I've been struggling to get through the work outs and getting in only about 4 different lifts. Is there any suggestions on how to rejuvenate my workouts so that I am able to get back through all my sets.
You may have stumbled with your sleep, eating, stress levels, amount of sunlight or socialization, or fallen into overtraining in a million other ways. Maybe your program simply has too much volume for you.
Regardless, it sounds like you're overtrained. Take a day or a week off, and when you start up again, consider doing dramatically less. Five days a week of lifting is often taxing. Sometimes more rest coupled with more intense lifting on the days when you do work out is easier on your recovery in the long term.
What are your goals? Do you have any goals? Goals should be a major part of any workout plan. Whether you want to be a world class athlete, compete well in a local event, improve stamina, lose some weight or maintain an energy level the lack of a goal can make working out a mental challenge.
If you have an athletic induced goal and you're stuttering to workout, post your goals somewhere to jump start you, be in on the inside of your bedroom door, your desk at work/school or in the car. If you do not have any try to find additional motivation to work out.
