How to structure 'Train Low' sessions into your own program?

Updated: Mar 19


As we’ve already alluded to, many athletes already inadvertently TL, often because of poor fuelling practices and therefore, have less of a need to implement this strategy into their own training programs. In fact, if you already spend a lot of training time in a low state, ironically you are likely to benefit more from performing a greater number of training sessions in a well-fuelled state!

If you’re looking to implement this type of training into your program, we would advise that you speak to a qualified sports nutritionist or coach before considering it as an option. We have offered Fitness Consultancy at TORQ since we were established in 1999 and we now cover this topic as part of our introductory Comprehensive Performance Package, so please contact us at enquiries@torqfitness.co.uk or phone 0344 332 0852 if you are interested in booking in with us. Here are a few key areas to address when considering programming TL sessions for an athlete:

How Often? – For athletes completing 5-6 days of training per week, undertaking multiple training sessions within a day, or having a generally high training volume, training low is inevitable, as it can be a challenge to consume sufficient food to meet the carbohydrate requirements of exercise. In this scenario, there is little need to program low training sessions into your week as it is likely to occur anyway. A focus on optimal fuelling is likely to be the best approach and an awareness of when your glycogen stores might be low, can help you to better manage the negatives of training low. Please note that if this situation sounds familiar to you, you should turn the sentiment of this article on its head and ensure that you schedule enough TH sessions into your program.

For the average athlete with limited time to train (say 3-4 sessions a week totalling 4-5 hours of training), it is important to maximise the time you have available by creating the greatest training stress possible. The inclusion of a 1-2 hour TL session could bring about aerobic benefits similar to a much longer well-fuelled session, so is the ideal approach for time-starved endurance athletes. However, limiting it to around 1-2 sessions at most will help ensure the balance between TH and TL training.

Training Intensity – Training low will increase the perceived exertion of a training session. It’s also impossible to tap into the anaerobic (high power output) system without a good supply of carbohydrate. To prevent this influencing the quality of the session, it is important to choose sessions that are not too prolonged or intense in nature. As mentioned earlier, an all-out interval session would be almost impossible or highly compromised when in a TL state, but a 1-2 hour low intensity ride would be perfectly targeted. Drinking a strong black coffee before the session, can help you through these sessions because of the benefit that caffeine can have on performance, particularly when fatigued. Rinsing a carbohydrate drink around your mouth without swallowing it has also been shown to help to reduce the perception of effort when glycogen stores are low, but don’t expect any miracles if you’re going to try this (Kasper et al., 2016).

Immune Function – A lack of carbohydrate can put your immune system under significant stress and leave you more at risk of illness and infection. If you complete the session well hydrated and avoid any unaccustomed training sessions, you can help limit the negative impact to the immune system and reduce the chances of picking up an illness or infection.

Protein Breakdown – Consuming around 20-25grams of a lean protein source, such as 2-3 scrambled eggs before a session can help to offset the breakdown of protein during a TL session and help keep hunger at bay. TORQ’s developing SNAQ range offers some practical solutions to this problem too, by providing some specifically designed high protein/low carb breakfast and meal options to be used in conjunction with these unique periodised sessions.

Recovery Meal – Training in a low state can help stimulate the muscles to respond and adapt in a way that is going to be advantageous to your aerobic system, however, for these adaptions to occur the body doesn’t just require the training stimulus, it also requires the nutrients for these adaptions to take place. It is therefore important to follow-up the training session immediately with a high-quality carbohydrate and protein recovery drink/meal to ensure the body has the nutrients required to create these adaptions.

Recovery Time – Completing a TL session can increase the amount of time it takes to recover in comparison to a well-fuelled session, so you will need to consume a carbohydrate and protein-rich diet for 24-48 hours if you’re wanting to follow up with a useful high intensity exercise bout. Selecting a session prior to a rest day would represent the ideal option. For this reason, it may also be best to avoid this type of training around competition too.

Take Home Message TL is a relatively new area of research and we can’t pretend to have all the answers, but we have drawn the following conclusions, which we hope will help you to make the right choices:

If you’re time-limited, periodising 1-2 TL sessions per week into your regimen may provide aerobic benefits over a 1-2 hour period that would otherwise require a longer ‘fuelled’ session. Combine these TL efforts with 2-3 well fuelled sessions.

If you’re an accomplished athlete with a significant amount of time available for training, you could still benefit from some TL sessions if you take some time to analyse at which points during your schedule your carbohydrate stores are likely to be naturally low, despite good fuelling practices. These would tend to be at the end of a run of high load training, leading up to a rest day and we feel that this should be an ideal time to put a ‘Low’ training session into your schedule. You can then follow it with a rest day, high carbohydrate diet and get back down to business. Be aware that if you’re not currently fuelling your training properly, you’re likely to get much bigger rewards by paying attention to this than any committed TL sessions.

If you’re a complete beginner or novice athlete, get a solid few months of training under your belt before you even start to consider something like this. A focus on optimal fuelling will help you enjoy your training and likely get more out of it in the early stages of your athletic career.

To summarise, TL is a tool that can help you to get more out of your training, but don’t expect magical results from it. The downsides must be very carefully managed to ensure that this method doesn’t negatively impact your training and remember, the key is, as with many things in life, all about ‘balance’. Also (and this can’t be stressed strongly enough) many people don’t fuel their training sessions properly anyway and are therefore undergoing a TL regimen without even realising it. Although this may provide associated benefits such as mitochondrial biogenesis, their performance will suffer because of inadequate fuelling for many of their sessions and lack of metabolic flexibility. These people would make huge gains through consuming more carbohydrate ahead of and during the training sessions that really depend on it as a fuel source. The vast majority of people who haven’t followed a structured fuelling regimen before and have gone on through our advice to increase their intake of carbohydrate-rich foods and use TORQ products, have made significant performance gains through increasing carbohydrate availability. Therefore, if you are going to schedule some TL sessions into your routine, it’s vital that you plan them properly and think about the bigger picture. A random approach is unlikely to get you very far and you would be much better off sticking to a high carbohydrate diet and fuelling every session properly.
