The truth is there is not any set time which is ideal to achieve results. The actual time that somebody should workout for varies greatly depending on a few factors.
So what are these factors?
- How many times a week you train.
- how many body parts you train in a single workout.
- Whether you are a beginner with little workout experience.
- How hard you train during your time.
- How much talking/socializing you do in the gym.
- What your goal is.
- Time spent warming up or cooling down.
- What training methods you are using.
- Time spent getting dressed and showering and so on!
- Also generally how much time you spend messing about before, after and during your workout.
- Genetics, metabolisms and things that are party beyond our control.
There is no such thing as an ideal workout time period! it just doesn’t exist, so once we accept that we can move forward.
Can we spend too much time in the gym?
Basically yes we can, we can overload our muscles which could limit our progress and even cause injury. However over training is not directly linked to how much time we spend in the gym. You could spend 2 hours or longer in the gym everyday and not over train, it just depends on how much actual training is being done in that time period.
Is a 30 minute workout long enough?
Yes most definitely, if you just kept your workout to a single body part, or focused on compound exercises then that could be enough to make decent gains in strength and muscle mass. However as mentioned above it does depend on the intensity of the training that is performed during that 30 minutes.
30 minutes is also a decent amount of time for a cardiovascular workout, training high intensity for 30 minutes can give your heart and lungs a good workout as well as burning off as many as 300+ calories.
On the flip side a 30 minute workout maybe too short to fit in a multi muscle targeted muscle building workout, it may not be enough time to sufficiently target those muscle groups in one workout.
So there really is not an ideal set time that you should be working out for and it would be a good idea not to focus on that.
The harder you train in your workout, the less time you will need to be at the gym to get the results you are looking for.
