Getting back in the gym after some time off can be challenging. You may feel the need to push yourself more in the first workout back to make up for lost time. This will most likely lead to increased muscle soreness causing you to miss the next workout.
Your first workout back should be focused on moving. This is not the time to lift really heavy or crush yourself with conditioning. Keep it short and sweet so you can get back into your normal routine.
Thinking long term can help in this situation. A few weeks off over the course of a year is nothing to be worried about. There’s no need to get frustrated or upset. Do your best to get back in the groove – take things slow and steady, just like you did when you first began training.
