Thanks, Chris, and good afternoon, everyone. I'm going to cover three topics before I get into our first quarter financials. The first is the state of the franchisees' balance sheets and their desire to reinvest into their Planet Fitness store portfolios. The second is our recurring revenue model and how it ties to our net membership growth; and third, our outlook for 2021 and beyond. On the first topic, we just completed business reviews with nearly all of our top 30 largest franchise groups that own the majority of our stores. The overall sentiment from the reviews was that our franchisees are very encouraged by the trends they are seeing across their stores and are eager to get back to our historical store growth levels. Almost all of the top 30 have debt, the majority of which tripped their debt covenants due to the temporary store closures last year. Those franchisees are all at different stages of paying deferred rent and building back their stores' profitability to the point where lenders make their development lines of credit available again. In some cases, that's already happened. In other cases, it will take more time because their stores were closed for a longer period of time. However, some of those franchisees are able to fund CapEx with cash from their balance sheet. The good news is franchisees and lenders are collectively becoming more bullish on expansion the longer the gyms are reopened and membership trends continue to move in the right direction. We expect franchisees to capitalize on the industry consolidation and more favorable real estate opportunities that are starting to emerge. With the pace of vaccine rollouts, we believe that the chances of a temporary shutdown on a national scale are less than when we reported our fourth quarter earnings in February, adding to our confidence in our projection of 75 to 100 openings in 2021. In Q1 this year, 22 new stores were open compared to 39 in Q1 last year. On to the second topic, our recurring revenue model. Beginning with our September sale last year, we have been focused on getting our marketing flywheel going again. As a reminder, our model and same-store sales results depend on the ability to continually grow net membership levels across our store base month over month, quarter-over-quarter and year-over-year. In our recurring revenue model, our same-store sales performance at any point is a function of what happened to our membership levels over the trailing 12 months in our comparable stores. We capitalized on the tailwinds that Chris talked about earlier and ramped up our membership acquisition-driven marketing throughout the first quarter of 2021. We ended March with approximately 14.1 million members, up 600,000 from where we ended 2020. And as Chris noted, it was our third consecutive month of sequential net membership growth. While an encouraging trend, it's hard to predict what the balance of the year will look like for membership growth as this is the first time that we have experienced this type of seasonality shift. With the economy growing and more and more states and municipalities lifting restrictions, we believe that there is positive momentum behind people wanting to become more active. As I mentioned, our system-wide same-store sales growth is a function of membership levels over the trailing 12 months. So while we are seeing signs in the near term of month-over-month net membership growth, our membership levels in our comparable stores are still below where they were in Q1 of last year when we hit an all-time high. As a result, same-store sales in the first quarter were down 14.9%, with franchise down 14.7% and corporate-owned down 18.2%. The decline was largely driven by the 1.4 million decline in membership levels year-over-year, slightly offset by an increase in average rate, which was driven by higher Black Card penetration. Black Card penetration increased to 61.2% at the end of Q1. As a reminder, we will not be reporting same-store sales growth figure in Q2 due to the majority of our store base being closed during Q2 last year. Lastly, I'd like to update our thoughts on guidance. On our Q4 call, we conveyed that we were not providing the typical metrics we guide on due to the continued uncertainty caused by the pandemic and feel that is still appropriate today. We did provide our new store development projections of between 75 and 100 new stores for the year, and as we announced last May, we provided franchisees with a 12-month extension on all of their development requirements and equipment placement obligations. In December, we extended the reequip commitments by an additional six months to a total of 18 months from the original due date. We want to give more insight into how we see those areas as a percentage of our total equipment revenue this year. Using the range of 75 to 100 new store openings this year, we expect that equipment replacement will be approximately 50% of our total equipment revenue this year. This is not a metric we will provide in the future, but we felt it was important during this period to try to provide additional insight into our equipment revenues and indirectly, into our franchisees' ability to fund their CapEx commitments, which is strong. Additionally, during this time, we continue to provide membership update for the months following our most recent quarter. As the year progresses and the effects of the pandemic start to wane, we will likely discontinue this practice and revert to providing the prior quarter's results only. Now on to our financial results. For the first quarter, total revenue was $111.9 million compared to $127.2 million in the prior year period. The $15.4 million decline was primarily driven by the lower equipment revenue, which was the result of the extensions that we've provided to our franchisees. Additionally, we deferred $24.6 million of revenue out of Q1's results last year due to the temporary closure of all of our stores as of mid-March. Moving on to a review of our segment revenue results. Franchise segment revenue was $64.1 million compared to $58.5 million in the prior year period, an increase of 9.5%. Let me break down the four components. First, royalty revenue, which consists of royalties on monthly membership dues and annual membership fees was $46.6 million compared to $40.6 million in the same quarter of last year. The average royalty rate for the first quarter for stores drafted was 6.3%, consistent with the same period last year. Note that the prior year period's royalty revenue was negatively impacted by a $14.1 million revenue deferral related to monthly membership dues collected in March shortly before stores closed. Next, our franchise and other fees were $4.8 million compared to $6.2 million in the prior year period. These are fees received from online new member sign-ups; the recognition of fees paid to us for franchise agreements, area development agreements and the transfer of existing stores; and fees received from processing dues. The decrease was primarily driven by lower total online join fees in the quarter. Also within the franchise segment revenue is our placement revenue, which was $0.8 million in the first quarter compared to $2.0 million a year ago. These are fees we receive for the assembly and placement of equipment sales to our franchisee-owned stores within the U.S. The decrease reflects the lower net store and reequip placements we executed in the quarter compared with a year ago. I will further discuss the number of new equipment placements later when I discuss equipment revenues. And finally, national advertising fund revenue was $11.6 million compared to $9.2 million last year. Similar to royalty revenue, the prior year period's NAF revenue was negatively impacted by $4.6 million deferral related to monthly membership dues collected in March shortly before stores closed. Our corporate-owned store segment revenue was $37.9 million compared with $40.5 million in the prior year period. The $2.6 million decrease was due to lower membership fees driven by lower membership levels and closure of some of our corporate stores for a portion of the period, partially offset by a $5.9 million of deferred revenue that was collected but not recognized in the three months ended March 31, 2020as a result of COVID-19 store closures and the opening of five new corporate-owned stores since January 1, 2020. Turning to our equipment segment. Revenue decreased $18.2 million or 64.7% to $9.9 million from $28.2 million. The decrease was driven by both lower new store equipment along with lower replacement equipment sales to existing franchisee-owned stores. Replacement equipment sales in Q1 were $1.1 million compared to $10.6 million in Q1 last year. In the first quarter, we had 18 new store equipment placements, which was down 12 from the prior year period. Our cost of revenue, which primarily relates to direct cost of equipment sales to new and existing franchise-owned stores, amounted to $8.0 million compared to $21.8 million a year ago, a decrease of 63.4%, in line with the equipment revenue decrease previously discussed. Store operation expenses, which are associated with our corporate-owned stores, decreased to $25.9 million compared to $26.2 million a year ago. The slight decrease was primarily driven by lower payroll and operating expenses, partially offset by higher rent and occupancy costs associated with the higher store count and marketing expense. SG&A for the quarter was $22.5 million compared to $17.0 million a year ago. The increase was primarily driven by higher incentive and stock-based compensation compared with the prior year period, local marketing support in California to accelerate the reopening of gyms and expenses to promote our mobile app. The California and mobile app expense were investments that we believe set us up for continued growth in both an important market as well as in our bricks-with-clicks digital strategy. National advertising fund expense was $12.8 million compared to $15.2 million in the prior year period. Adjusted EBITDA was $43.7 million compared to $46.5 million in the prior year period. A reconciliation of adjusted EBITDA to GAAP net income or loss can be found in the earnings release. By segment, franchise adjusted EBITDA was $41.3 million, corporate store adjusted EBITDA was $11.2 million and equipment adjusted EBITDA was $1.8 million. Adjusted net income was $9.1 million, and adjusted net income per diluted share was $0.10 or a decrease of $0.06 per diluted share. Now turning to the balance sheet. As of March 31, 2021, we had total cash and cash equivalents of $503.9 million compared to $515.8 million on December 31, 2020. This was comprised of cash and cash equivalents of $445.6 million compared to $439.5 million with $58.3 million and $76.3 million of restricted cash, respectively, in each period. Total long-term debt excluding deferred financing costs was $1.79 billion as of March 31, 2021, consisting of our three tranches of securitized debt and $75 million of variable funding notes. Our securitized debt structure is covenant-light. We have two maintenance covenants: a debt service coverage ratio and a total system-wide sales threshold. Both are tested quarterly, calculated on a trailing 12-month basis and reported roughly on a 2-month lag. In our most recent debt covenant reporting period of March 5, 2021, we had a 17% and a 93% cushion to the first triggering event for our debt service coverage ratio and system-wide sales covenant, respectively. We believe we have sufficient headroom for our two maintenance covenants, especially now with the majority of our stores open. The unprecedented pandemic situation in 2020 proved the durability of our business model. Our stores were closed between two and nine months last year, and we did not have a single permanent closure due to COVID. Additionally, during our franchise business reviews, franchisees have reported that while their store EBITDA levels has decreased, many of them still have EBITDA percent margins in the 30s for their mature stores. I believe that as we emerge from the pandemic, our investment thesis has only been strengthened with the critical importance of health and wellness on the rise. We are a differentiated and disruptive fitness concept that appeals to a broad demographic with a national scale advantage built on strong store-level unit economics, and we believe our competitive moat will continue to widen as we begin to come out of and get to the other side of this awful pandemic. I'll now turn the call back to the operator to open it up for Q&A.
