Sweat lists the 20% off membership voucher at the top of this page as its lead offer, so the featured voucher is the simplest route to take 20% off your selected membership plan; it is best for you if you already know which plan you want and you can enter a code at checkout. The voucher cannot be combined with other promotional offers, so it suits shoppers who want a straightforward discount on their chosen membership.
If you plan to commit for a year pick the annual plan for $134.99 each year. That is the clearest lowest price on the page for long term access and works well if you are confident you will use the app regularly. On a $134.99 annual purchase there is no extra discount to apply, so the cost is $134.99 and your saving from other offers is $0. (Original $134.99, discounts none, final $134.99, saving $0.)
If you want the longest risk free trial before paying use one of the 14 day free trial offers that pair a two week trial with 20% off specific plans, for example the Strength and Pilates program or running training plans. These deals give you two weeks free, then take 20% off the plan price when the trial ends. This is the best pick if you want to try the training style and then keep a discounted subscription.
If you only need a short look around take the 7 day free trial. It gives you one week of access to try workouts with no upfront payment. Choose this if you prefer a shorter test before deciding which plan to buy.
If you want a discount on individual workouts or program purchases rather than a membership the site sale of 20% off all workouts applies to items marked down on the website. That sale is priced as marked and runs while stock lasts, so it is the option to use when you buy single programs or workout packs instead of subscribing.
If you plan to use the featured voucher remember it applies to the membership plan you select and cannot be combined with other promotional offers. The 14 day trial plus 20% offers are better when you want a free trial up front, while the annual $134.99 plan is the lowest explicit dollar price if you are ready to commit for a year. Take whichever option leaves you the lower total for the same plan and billing period; if you use the voucher, do not expect to stack it with the trial discount or other promotions unless the terms on the brand site say otherwise.
