Having trouble getting to the gym? Well if you’re not a fan of overstimulating pre-workouts and expensive supplements in general, you may want to try smoking weed before the gym.

While smoking does have a somewhat unwarranted reputation for making its users lazy and tired, that’s not always the case.There are certain strains that can invigorate its users with a cerebral, energetic high that provides not only the perfect motivation to hit the gym, but gives you the energy needed for a killer workout. The best part about smoking weed before a workout—it’s all natural, unlike your standard over-the-shelf supplements. So, without further ado, here are the top 10 strains to improve your workout.

Sour Cheese is a hybrid that bestows its users with a nice balanced high—a perfect mix of high energy and a relaxed mental state. Being slightly sativa-dominant (around 60/40), it should provide the user with enough juice to get through a workout, without making you crash towards the end of it.

Another sativa-dominant hybrid, Super Lemon Haze is sure to give you more than enough energy, and its cerebral effects will certainly motivate someone to hit the gym. Be warned, however—it has a pretty high THC level at around 25 percent, so don’t smoke too much of this stuff before the gym, or you might just be too high to have a good workout.

Orange Diesel is another sativa-dominant strain (see the pattern here?), and it is frequently used to treat ADD or ADHD in medicinal patients. If you have trouble focusing, or getting yourself to get through a workout, this could be the perfect strain for you. A couple of puffs of this, and you should find the energy within yourself to climb a mountain. Or just get out of bed. Either way works.

Harlequin is another sativa-dominant hybrid, but it boasts a much higher sativa to indica ratio than the other strains to improve your workout at 75/25 percent. Additionally, it contains a 5:2 ratio of CBD: THC, so you will feel a huge rush of energy, without getting too stoned. This strain might feel like a workout, rather than a strain of weed if you smoke just the right amount.

Lemon Sour Diesel is one of the more classic strains of weed, and it also happens to be one of the perfect strains to improve your workout. Diesel will give its users a euphoric, cerebral high, so it could be perfect for doing yoga, or any other exercise that requires the strength of mind above all else.
